* Implemented instancing for the drawInstanced test and confirmed that test values taken at specific pixel location match expected values
* Removed writeImage() helper function as this is for debugging only
* Factored out shared test code and wrapped tests inside a base class with derived structs for each individual draw call variant; Added a test for indexed, instanced draws but test is currently not working correctly
* Indexed instancing test finish and working; Further refactor to move code that fills the test result array and creates the vertex and color buffers to the base test class
* Commented out image dump helper function at the top as it may still be needed for the remaining draw tests
* Added a new struct derived from the base test class for testing indirect but non-indexed draws; Moved required command signatures for indirect draws into D3D12Device to ensure they continue to exist outside of their respective draw calls; Moved command signature creation into D3D12Device::initialize(); Small consistency cleanup changes
* Added working indexed indirect draw call test
* Moved expectedResult and compareComputeResult() call into getTestResults() and renamed to checkTestResults()

* Various Fixes to gfx, reflection and emit.
- Fix GLSL emit to properly output `*bitsTo*` functions for `IRBitCast` insts.
- Add line directive mode setting for `ISession`.
- Extend `TypeLayout::getElementStride` to handle `VectorType` case.
- Fix `IDevice::readBufferResource` 's D3D12 implementation to copy only the requested bytes out.

* Cleanup work on D3D12 shader object static specialization
This builds on PR #1829 in a small way (because that PR adds `getStride()` to Slang type layout reflection). The only relevant changes here are in the `render-d3d12.cpp` file.
The basic idea here is to clean up the D3D12 path to be more in line with the cleanups made for D3D11 and Vulkan. The way that D3D12 shader parameter binding goes through a root signature means that some of the details that were required for those APIs (in particular, tracking both "primary" and "pending" offsets during multiple steps) are not required for the critical-path binding stuff on D3D12.
There is some subtlety to the handling of the "ordinary" data buffer in the `bindAsValue()` case that I don't like, and that I'm not 100% confident I've gotten right. We may find that we have to revisit that logic as we add more tests.
* fixup

* 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.
