Changed the interface from `IEntryPoint::getRenamedEntryPoint` to `IComponentType::renameEntryPoint`.
The underlying implementation creates a `RenamedEntryPointComponentType` wrapper object around the base entry-point.
This new implementation allows the user to specify entry point renaming on an IComponentType that isn't just a `EntryPoint`, but also on `SpecializedComponentType` or `CompositeComponentType` as long as the component defines a single entry point.

This change applies to the case where we have a sub-object range with more than one object in it (so arrays of constant buffers, parameter blocks, or existentials). It is worth noting that we don't really seem to have any tests covering this case right now, so it is entirely possible that things are busted already, and/or that this change doesn't work the way I think it does.
When we go to actually bind the state from a sub-object range into the pipeline, we care about:
* The offset to where the first object should be written
* The "stride" between consecutive objects
We were already capturing the offset information from Slang reflection data, and the same was true for the part of the offset that pertains to "pending" ordinary data. For other cases, though, we were manually incrementing the offset by values computed manually in `gfx` for Vulkan, and we were just skipping the offsetting step entirely for D3D11.
With this change we extract more complete stride information from the Slang reflection data and use that instead of ad hoc computations. Hopefully this data is correct, and if it isn't we can consider whether it needs fixing at the Slang reflection level rather than in `gfx`.
This change doesn't apply to the OpenGL back-end (which hasn't been updated to match the new approach to static specialization at all) or to the D3D12 back end (which has been updated a bit, but probably needs other cleanup work to be done first to bring it in line).
|

* Update gfx back-ends to handle static specialization
The main goal here is to make the D3D11, D3D12 and Vulkan back-ends support static specialization of interface types in the case where the data for the type won't "fit" in the pre-allocated space for existential values. This includes all cases where the concrete type being specialized to has resources/samplers/etc., as well as any cases where its ordinary/uniform data exceeds the space available.
(Note that the CPU and CUDA targets don't need this work since they can (in theory) support arbitrary-size data in the fixed-size existential payload by using pointer indirection. Actually supporting indirection in those cases should be a distinct change)
The Slang compiler already performs layout for programs that have this kind of data that doesn't "fit," and it lays them out using an idea of "pending" type layouts. Basically, a type that contains some amount of specialized interface-type fields will produce both a "primary" type layout that just covers the data for the unspecialized case, as well as "pending" type layout that describes the layout for all the extra data needed by specialization.
When laying out a `ConstantBuffer<X>` or `ParameterBlocK<X>` ("CB" or "PB"), the front-end will try to place as much of that "pending" data into the layout of the buffer/block itself as is possible. That means that both CBs and PBs will be able to allocate trailing bytes for any ordinary data in the "pending" layout. PBs will be able to allocate any trailing resources/samplers into their layout, but for CBs they will spill out to be part of the pending layout for the buffer itself.
In order for the back-ends to properly handle pending data, they need to *either* assume the exact layout rules used by the front-end and try to reproduce them (e.g., by iterating over binding ranges and sub-objects in the exact same order that front-end layout would enumerate them), *or* they need to respect the reflection information produced by the front-end. This change takes the latter approach, trying to make only minimal assumptions about the layout rules being used. This choice is motivated by wanting to decouple the `gfx` implementation from the compiler front-end, especially insofar as this work has made me question whether the current layout rules are the best ones possible.
A common theme across all the implementations is to have a fixed-size type that can represent "binding offsets" for the chosen back-end. The offset type has fields that depend on the API-specific way bindings are indexed; e.g., for D3D11 it has offsets for CBV, SRV, UAV, and sampler bindings. This fixed-size offset type can be filled in based on Slang reflecton information, and then used to compute derived offsets with just a few add operations.
The simple offset type for each API is then extended to produce an offset type that includes both the offsets for "primary" data and also the offsets for "pending" data. Most logic that traffics in offsets doesn't have to know about this more complicated representation.
Making consistent use of these offsets required that I pretty much rewrite the logic that actually applies shader objects to the API state. Doing so might be lowering the efficiency of the system in the near term, but the increase in clarity was important for getting the work done, and it seems like it will also be important if/when we start trying to perform special-case optimizations around root and entry-point parameter setting.
While there are many API-specific differences, we can identify a repeated pattern where many steps, whether applying parameters to the pipeline stage or constructing signatures / layouts, can be broken down into three main operations on `ShaderObject`s or their layouts:
* `*AsValue()` is the core operation, and is the one used for the `ExistentialValue` case most of the time. It ignores the ordinary data in the object, and instead processes all nested binding ranges (for resources/smaplers) and sub-objects.
* `*AsConstantBuffer()` handles the `ConstntBuffer<X>` case, by dealing with the implicit buffer for ordinary data (if it is needed) and then delegates to the `*AsValue()` case.
* `*AsParameterBlock()` handles the `ParameterBlock<X>` case, by allocating/preparing/etc. any descriptor tables/sets that would be required for the current object/layout and then delegating to `*AsConstantBuffer()` to do the rest
The idea is that by having the parameter block case delegate to the constant buffer case, which delegates to the value/existential case, we can streamline a lot of the logic so that it doesn't seem quite as full of special cases.
Note: When preparing this pull request I spent a reasonable amount of time trying to clean up the D3D11 and Vulkan implementations, so they are probably the easiest to read and understand when it comes to the new code. Doing the cleanup work also helped to work out some weird corner case bugs/issues. In contrast, the D3D12 path hasn't had as much attention given to cleanliness and comments, so it really needs some attention down the line to get things into a state that is easier to understand.

* Fixing `PseudoPtr` legalization and `gfx` lifetime issues.
* Fixing `model-viewer` example.
This change contains various fixes to bring `model-viewer` example to fully functional. These fixes include:
1. Add `spReflectionTypeLayout_getSubObjectRangeSpaceOffset` function to return the space index for a sub object referenced through a `ParameterBlock` binding.
2. Make sure `D3D12Device` specifies column major matrix order creating a Slang session.
3. Fix `platform::Window::close()` and `platform::Application::quit()`.
4. Fix memory leak during `model-viewer''s model loading.
5. Fix command buffer recording in `model-viewer`.
With these changes, model viewer can now produce an image with a gray cube. The lighting is still incorrect becuase the `gfx` shader object implementation still does not handle "pending layout" resulting from global existential parameters.
* Fix d3d12 root signature creation.
* Use row-major matrix layout in model-viewer

This change originated as an attempt to re-enable a test case, but it has ended up disabling more tests (for good reasons) than it re-enables.
The main change here is a significant overhaul of the way that the D3D12 render path extracts information from the Slang reflection API to produce a root signature.
There were also some supporting fixes in the reflection information to make sure it returns what the D3D12 back-end needed.
The big picture here is that the D3D12 path now uses the descriptor ranges stored in the reflection data more or less directly.
It still needs to use register/space offset information queried via the "old" reflection API, but it only does so at the top level now, for the program and entry points themselves.
All other layout information is derived directly from what Slang provides.
Smaller changes:
* The "flat" reflection API was expanded to include `getBindingRangeDescriptorRangeCount()` which was clearly missing.
* The "flat" reflection results for a constant buffer or parameter block that didn't contain any uniform data and was mapped to a plain constant buffer needed to be fixed up. That logic is still way to subtle to be trusted.
* Several additional tests were disabled that relied on static specialization, global/entry-point generi type parameters, structured buffers of interfaces or other features we don't officially support with shader objects right now. All of the affected tests were somehow passing by sheer luck and because they often passed in specialization arguments via explicit `TEST_INPUT` lines.
* The `inteface-shader-param` test is re-enabled now that we can properly describe its input with the new `set` mode on `TEST_INPUT`
* `ShaderCursor::getElement()` can now be used on structure types (in addition to arrays) to support by-index access to fields
* The `TEST_INPUT` system was expanded to support both by-name and by-index setting of structure fields for aggregates
* The `TEST_INPUT` system was expanded to allow an `out` prefix to mark parts of an expression as outputs on a `set` lines
* The `TEST_INPUT` system was expanded so that anything that would be allowed on a `TEST_INPUT` line by itself (like `ubuffer(...)`) can now be used as a sub-expression on a `set` line

* Add a CPU renderer implementation
This change adds a CPU back-end to `gfx` and ensures that most of our existing CPU tests pass when using it.
Detailed notes:
* Most of the CPU renderer implementation is copy-pasted from the CUDA case, so they share a lot of similar logic
* The main addition to the CPU renderer is a semi-complete implementation of host-memory textures. The logic here handles all the main shapes (Buffer, 1D, 2D, 3D, Cube) and all the currently-supported `Format`s that are sample-able as-is (no D24S8). The implementation is not intended to be fast, and it currently only does nearest-neighbor sampling, but otherwise it tries to avoid cutting too many corners and should be ar reasonable starting point for a more complete (but not performance-oriented) implementation.
* Refactored the CPU prelude `IRWTexture` interface to inherit from `ITexture`, since in most cases a single type will end up implementing both. It might be worth it to collapse it all down to a single interface later.
* Changed the CPU prelude `ITexture`/`IRWTexture` interface so that it takes both a pointer *and* a size for output arguments. This change seems necessary to allow a shader variable declared as a `Texture2D<float>` to fetch a single `float` when the underlying texture might be using RGBA32F.
* Added to the `IComponentType` public API so that we can query a "host callable" for an entry point and not just a binary.
* Turned off the `-shaderobj` flag on two tests that weren't yet compatible with shader objects but still had the flag left in on the path (since previously the CPU path always used the non-`gfx` non-shader-object logic anyway)
* Disabled one test (`dynamic-dispatch-11`) that relied on the `ConstantBuffer<IInterface>` idiom that we know we are planning to chagne soon anyway.
* Made a few changes to the CUDA path to bring it into line with what I added for the CPU path. These were mostly bug fixes around indexing logic for sub-objects and resources.
* fixup

* Use "capability" system to select VKRT extension
Slang currently supports translation of ray tracing shader code to Vulkan GLSL code that uses the `GL_NV_ray_tracing` extension. A multi-vendor equivalent of that extension has been released as `GL_EXT_ray_tracing` and we want Slang to support that extension as well.
At the simplest, making the change from one extension to the other is just a matter of changing a few strings, since it does not appear that anything of significance was changed at the GLSL level (or even in SPIR-V). Where this gets trickier is when we have users who want us to support *both* extensions, and to be able to switch between them.
The solution we've implemented here more or less amounts to:
* If you don't tell the compiler which extension to use, it will default to `GL_EXT_ray_tracing` (the newer multi-vendor one).
* If you explicitly want the older extension, you can opt into it using the `-profile` option or via a new API for explicitly adding capabilities to your target.
Making that work required a few different kinds of changes:
* The options parsing and public API needed ways to add optional capabilities to a target.
* During GLSL code emit, we can check the capabilities that were added to the target to see if the `GL_NV_ray_tracing` extension was explicitly enabled and, if not, default to using the `GL_EXT_ray_tracing` names for things. This step is needed because some of the modifiers/attributes involved in the extension have to be handled explicitly in the code generator rather than implicitly as part of mapping intrinsic functions.
* We add two different translations to the relevant operatiosn in the stdlib, one marked with each of the extensions. If profile/capability-based overload resolution can be relied on to pick the right one, this should Just Work.
* Next, a bunch of work had to go into making capability-based overloading Just Work for the purposes of this change. There's been a nearly complete reworking of the implementation of `CapabilitySet` here to make it more suitable for our needs.
* The tests that were using ray tracing translation for Vulkan needed to be updated. For some of them I updated their baselines to use `GL_EXT_ray_tracing` so that they can test the new path. For others, I updated the command line for the test case so that it explicitly opts into using `GL_NV_ray_tracing`. The result is that we have some coverage of each extension. I would have liked to have each test run in both modes, but our pass-through glslang support doesn't support `-D` options, so I couldn't take that step easily.
This change does *not* add support for `GL_EXT_ray_query`, the extension that supports "DXR 1.1" style queries under Vulkan. Adding support for that extension should hopefully be a smaller step because it doesn't have the same multiple-extensions issue.
This change does *not* address a lot of possible avenues for improvement or cleanup around the capability system. It focuses only on those changes that are necessary to make the ray tracing feature work and leaves the rest for future work.

This was a serious problem that meant that some of our public API functions (exported from the DLL) had mangled C++ symbol names (which are not guaranteed to be portable across different compilers).
The fix here is the expedient one: just add `extern "C"` to the relevant functions. The simplicity has a cost, though, in that this change introduces a significant break in binary compatibility.
Source code should be compatible before/after this change, but it would be necessary to match an application and Slang shared library so that they agree on the mangled names of these symbols. We will need to treat this as a breaking release when this change goes out.
Note that because of the way that C++ mangled names were being used, we *already* have introduced breaking changes to the binary interface in a recent change that made `SlangCompileRequest` into a `typedef` instead of a forward-declared `struct` type. To be clear, the breakage was due to the missing `extern "C"` and *not* the content of that change; the change would have been binary-compatible if the symbol names were correct.
Given that the cat is out of the bag to some extent (our next release is going to break compatibility one way or another), it seems best to just get the whole thing sorted at once.

This change adds a single new entry point to our reflection API that allows an application to query the `TypeLayout` that represents the global-scope shader parameters. This can be used by the application in order to detect when the global parameters have required allocation of a default constant buffer, or simply to unify the handling of the global scope with handling of other kinds of parameters.

|
* Add API for whole program compilation.
This change exposes a new target flag: `SLANG_TARGET_FLAG_GENERATE_WHOLE_PROGRAM` that can be set on a target with `spSetTargetFlags`. When this flag is set, `spCompile` function generates target code for the entire input module instead of just the specified entrypoints. The resulting code will include all the entrypoints defined in the input source.
The resulting whole program code can be retrieved with two new functions: `spGetTargetCodeBlob` and `spGetTargetHostCallable`.
This change also cleans up the unnecessary `entryPointIndices` parameter of `TargetProgram::getOrCreateWholeProgramResult`, and modifies the `cpu-hello-world` example to make use of the new whole-program compilation API to simplify its logic.

* Export witness table objects in compiled code.
- Ensure that witness tables are preceeded with `extern "C"` modifier in the generated C++ code.
- RTTI objects use the mangled name of the type directly, so that can be queried using the type's mangled name directly from the resulting DLL.
- Expose `Linkage::getTypeConformanceWitnessMangledName` to return the mangled name of witness tables to the host.
- Ensure that all witness tables (including those for associated types) have proper mangled name.
* Fix GCC error in Slang generated code.
