Every shader now has the ability to declare which payload it uses. HitGroup, Miss and Callable shaders may only specify a single type, whereas Raygen shaders may provide more than one.
The global raytracing shader libraries have been categorized according to their payload type, which helps facilitate the creation of minimal ray-tracing pipelines.
Avoid adding callable shaders to the RTPSO if they are not being used.
All RHI shader compilers and shader loaders that support ray tracing have been modified to track an extra uint representing the payload type flagged in the source (at time of compilation).
Add the RayTracingPayloadType to the shadermap DDC key so that we can properly detect when a shader's payload type is invalidated. This is required because we serialize the payload type into the shaders from the C++ side.

- Making ConstantBufferType a constructor only argument. This removes the duplicated logic of calling ShouldUseStableConstantBuffer.
- Moving ShouldUseStableConstantBuffer to ShaderCompilerCommon.
- Made UE::ShaderCompilerCommon::ParseParameterType array arguments const

- Instrument how long shader preprocessing takes for each shader compilation job.
- Keep a running total in our shader stats per shader type.
- Add logging to track total thread preprocessing time for all shaders.
- Fixup local variable names to match the output log names.

This allows to iterate to compile the USF file to SPIRV and translate to GLSL to verify the sanity of the SPIRV assembly.

- Refactoring FShaderParameterParser to use more string views since we can rely on OriginalParsedShader not changing.
- Split FShaderParameterParser::ParseAndMoveShaderParametersToRootConstantBuffer into smaller functions
- Moving FShaderParametersMetadata::IterateShaderParameterMembers into the only module it's used in, ShaderParameterParser.cpp
- Adding CFLAG_BindlessResources which will be set when ENABLE_BINDLESS_RESOURCES is set
- Adding CFLAG_BindlessSamplers which will be set when ENABLE_BINDLESS_SAMPLERS is set
- Adding resource/sampler detection and conversion to bindless in FShaderParameterParser

This is a prerequisite for upcoming bindless changes as it centralizes key points where we register the different binding types.

- use STORAGE_IMAGE to read from R64 formats when sampling isn't supported.
- leave high level code and HLSL untouched (RDG will continue to consider them read only access), patch SPIRV instead
- create a codepath for hzb that uses UlongType
- update shader guid for Vulkan to force rebuild
Fixes all validation issues with 64bit atomics and allows the use of RADV driver (AMD+Linux) for Nanite/Lumen.
