* Significantly reduces the size of shader debug data and improves shader compilation time (reducing parsing cost in the native shader compiler)
* Remove "experimental" label for the feature

RHI header dependency cleanup
- Reducing other header dependencies from RHIDefinitions.h
- Moved a few functions to the new RHIStrings.h
- Uniform buffer layout initializer moved to its own file to reduce RHI dependency on MemoryLayout.

* Not enabled in Metal and OpenGL back-ends (require further testing)

- SM6.0+ shader reflection now checks for D3D_SHADER_REQUIRES_STENCIL_REF and sets EShaderCodeFeatures::StencilRef if it's set.
- D3D12 initialization now correctly sets GRHISupportsStencilRefFromPixelShader.
- D3D12 shader loading makes sure that EShaderCodeFeatures::StencilRef shaders are only loaded when GRHISupportsStencilRefFromPixelShader is set.

Serialize the payload size as part of the raytracing shader so it can be examined in the RHI layer.
Validate that the RTPSO is configured with the appropriate payload size.
Add macros to ensure the payloads have the expected size
Ensure that all raytracing pipelines explicitly bind a miss shader
Add a shared shader header to implement static asserts for those shader compilers that support them (like dxc).
Fix payload type on main deferred reflection raygen shader
Fix incorrect raygen shader included in the deferred RTPSO list for RTGI
Don't add builtin shaders to the RTPSO from the RHI layer as these are unlikely to ever match the required payload type
Add new method to register payload types so that plugins can more easily describe custom payloads they may be using (up to a maximum of 32 unique payload types since we use a bitmask to represent payload sets).

- No longer necessary, since they were only used to find/create root signatures, which can be implemented directly in the adapter class.
- RHICreateBoundShaderState is never called.
Remove D3D12_SUPPORTS_PARALLEL_RHI_EXECUTE
- This is always true.

- All platforms were extending FBaseShaderResourceTable to add a TArray<uint32> TextureMap member, along with copies of the same RHI code to bind these resources.
- Moved the TextureMap member into the base shader table type, and removed all platform versions. They are all serializer-compatible with the original code, so no shader DDC keys need to be bumped.
- Also moved the "ResourceTable" array of RHI resources into the base FRHIUniformBuffer class.
- Added a SetResourcesFromTables function in RHICoreShader.h
Removed GetD3D11TextureFromRHITexture in D3D11RHI, replaced with a ResourceCast.
- The ResourceCast function for FRHITexture types now always follows the texture reference pointer via the vtable call, like other platforms.
