* Add command-line control over SPIR-V version
By default the Slang compiler policy is usually to produce output with the fewest dependencies possible. If input code can be encoded as SPIR-V 1.0, that is what we will use by default. The catch here is that in some cases later SPIR-V versions introduced improvements to the encoding that can affect performance (e.g., around large global arrays of constants), so that a user might explicitly want to require a newer SPIR-V version (restricting the driver versions their code can work on) in the hopes of seeing better performance.
This change uses the system of capabilities that was previously introduced so that an option like `-profile glsl_450+spirv_1_5` can be used to explicitly request a specific SPIR-V version. Consistent with the existing implementation, the requested version will be taken as a minimum, and the final version might be higher based on other requirements (e.g., use of intrinsic functions that require a higher version).
The test case included here is a little iffy in terms of long-term maintanenace. It relies on having both a `.slang` file and a `.glsl` file that we compile with the same options and then compare the SPIR-V, but that means there is no direct testing that the output SPIR-V actually uses the necessary version. If we break the inference of SPIR-V versions for both the regular and pass-through paths at once, this test won't flag the problem. A better test is probably needed soon.
This change *only* adds support for controlling the SPIR-V version via capabilities specified via the command line or API. It would be nice to a future change to allow something like `[require(spirv_1_5)]` to be added to an entry point function to allow the user to embed their expectation/requirement into the source code.

* 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.

* 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.

* Search for multiple NVRTC versions
The main change here is that when locating the NVRTC compiler we try multiple library names and take the first one that loads successfully (with an ordering that means we try newer versions before older ones).
In order to support this change, I needed to fix the wrapping logic that invokes the downstream compiler "locator" function, so that it does not report every failed dynamic library load as an error diagnostic (leading to compilation failure), but instead only reports such failures once the locator has reported failure.
The form of the diagnostic output for failures is also changed, in that we now report a single umbrella error about failing to load a downstream compiler, and then report the actuall dynamic library load failures as notes on that diagnostic instead of errors of their own. This choice seems appropriate since for cases like NVRTC it is *not* the case that each failed library load is a compilation error. We only need one of the listed libraries to be loadable, so that reporting them all as errors risks confusing users.
One wrinkle that arose during testing is that the 11.0 release of NVRTC dropped support for the `compute_30` target, which had previously been the minimum and default. I had to add logic to check for versions of 11 or greater and switch to `compute_35` as the default. Similar changes may be required as part of supporting newer NVRTC versions if support for more architectures gets deprecated and removed.
A more complete implementation of this logic might try to load multiple NVRTC versions such that the Slang compiler can identify a suitable compiler based on the minimum feature level that code actually requires. That kind of cleanup is left as future work, since for most users the current approach will be sufficient.
* testing: use verbose mode for running tests by default
* fixup: guard against null diagnostic sink

The refactorings that added support for multiple entry points in an output file seemingly introduced a regression such that we crash on compilation that is not "end-to-end." Unfortunately, all of our testing only covers end-to-end compilation, and many users only use that mode.
I've added a fix for the issue I ran into, but I haven't addressed the testing gap in this change. Without adding testing for non-end-to-end compilation, I expect further regressions to slip in over time.

Improved handling of loadFile - uses uniqueId if has one.
* Work around for testing target overlaps - to avoid exceptions on adding targets.
Simplify PathInfo setup.
Modify single-target-intrinsic.slang - it no longer failed because there were no longer multiple definitions for the same target.

* Initial work to support OptiX output for ray tracing shaders
This change represents in-progress work toward allowing Slang/HLSL ray-tracing shaders to be cross-compiled for execution on top of OptiX. The work as it exists here is incomplete, but the changes are incremental and should not disturb existing supported use cases.
One major unresolved issue in this work is that the OptiX SDK does not appear to set an environment variable
Changes include:
* Modified the premake script to support new options for adding OptiX to the build. Right now the default path to the OptiX SDK is hard-coded because the installer doesn't seem to set an environment variable. We will want to update that to have a reasonable default path for both Windows and Unix-y platforms in a later chance.
* I ran the premake generator on the project since I added new options, which resulted in a bunch of diffs to the Visual Studio project files that are unrelated to this change. Many of the diffs come from previous edits that added files using only the Visual Studio IDE rather than by re-running premake, so it is arguably better to have the checked-in project files more accurately reflect the generated files used for CI builds.
* The "downstream compiler" abstraction was extended to have an explicit notion of the kind of pipeline that shaders are being compiled for (e.g., compute vs. rasterization vs. ray tracing). This option is used to tell the NVRTC case when it needs to include the OptiX SDK headers in the search path for shader compilation (and also when it should add a `#define` to make the prelude pull in OptiX). This code again uses a hard-coded default path for the OptiX SDK; we will need to modify that to have a better discovery approach and also to support an API or command-line override.
* One note for the future is that instead of passing down a "pipeline type" we could instead pass down the list/set of stages for the kernels being compiled, and the OptiX support could be enabled whenever there is *any* ray tracing entry point present in a module. That approach would allow mixing RT and compute kernels during downstream compilation. We will need to revisit these choices when we start supporting code generation for multiple entry points at a time.
* The CUDA emit logic is currently mostly unchanged. The biggest difference is that when emitting a ray-tracing entry point we prefix the name of the generated `__global__` function with a marker for its stage type, as required by the OptiX runtime (e.g., a `__raygen__` prefix is required on all ray-generation entry points).
* The `Renderer` abstraction had a bare minimum of changes made to be able to understand that ray-tracing pipelines exist, and also that some APIs will require the name of each entry point along with its binary data in order to create a program.
* The `ShaderCompileRequest` type was updated so that only a single "source" is supported (rather than distinct source for each entry point), and also the entry points have been turned into a single list where each entry identifies its stage instead of a fixed list of fields for the supported entry-point types.
* The CUDA compute path had a lot of code added to support execution for the new ray-tracing pipeline type. The logic is mostly derived from the `optixHello` example in the OptiX SDK, and at present only supports running a single ray-generation shader with no parameters. The code here is not intended to be ready for use, but represents a signficiant amount of learning-by-doing.
* The `slang-support.cpp` file in `render-test` was updated so that instead of having separate compilation logic for compute vs. rasterization shaders (which would mean adding a third path for ray tracing), there is now a single flow to the code that works for all pipeline types and any kind of entry points.
* Implicit in the new code is dropping support for the way GLSL was being compiled for pass-through render tests, which means pass-through GLSL render tests will no longer work. It seems like we didn't have any of those to begin with, though, so it is no great loss.
* Also implicit are some new invariants about how shaders without known/default entry points need to be handled. For example, the ray tracing case intentionally does not fill in entry points on the `ShaderCompileRequest` and instead fully relies on the Slang compiler's support for discovering and enumerating entry points via reflection. As a consequence of those edits the `-no-default-entry-point` flag on `render-test` is probably not working, but it seems like we don't have any test cases that use that flag anyway.
Given the seemingly breaking changes in those last two bullets, I was surprised to find that all our current tests seem to pass with this change. If there are things that I'm missing, I hope they will come up in review.
* fixup: issues from review and CI
* Some issues noted during the review process (e.g., a missing `break`)
* Fix logic for render tests with `-no-default-entry-point`. I had somehow missed that we had tests reliant on that flag. This required a bit of refactoring to pass down the relevant flag (luckily the function in question was already being passed most of what was in `Options`, so that just passing that in directly actually simplifies the call sites a bit.
* There was a missing line of code to actually add the default compute entry points to the compile request. I think this was a problem that slipped in as part of some pre-PR refactoring/cleanup changes that I failed to re-test.
