- Bindless rendering is not enabled anywhere yet.
- Adding bSupportsBindless to DDSPI.
- Moving ED3D12DescriptorHeapType into RHI and renaming to ERHIDescriptorHeapType.
- Adding FRHIDescriptorHandle for public usage of bindless indices.
- Adding GetBindlessHandle() to RHI SamplerState, SRV, UAV.
- Adding GetDefaultShaderResourceView() to RHI Textures.
- Adding bindless Sampler heap support to D3D12.
- Cleaned up some common shader code in prep for future bindless work.

Also remove further references to Hull and Domain shaders as tessellation is no longer supported in UE5.

- Splitting symbol generation and shader "debug info" generation into two different cvars. This should now allow us to generate symbols post-packaging without generating different shader variants. This should also enable us to always generate symbols and still have the final deduplicated shader sizes.
- r.Shaders.Symbols is now the primary way to enable shader symbols for debugging.
- r.Shaders.GenerateSymbols can be enabled to always generate symbols without writing them to disk.
- r.Shaders.WriteSymbols can be used to force write symbols if they were previously generated.
- r.Shaders.ExtraData can be used to generate shader names for engine runtime systems to use.
- NotifyShaderCooked replaced with NotifyShaderCompiled, prep for upcoming non-cook symbol writing.
- PC DXC shader compiles should only generate debug info when requested, not all the time.
- PC FXC shader compiles should generate debug info when requested, not just when r.Shaders.Optimize is 0.

Add ray tracing shader types
Add initial ray tracing pipeline creation
Add acceleration structure descriptor type
Add basic ray tracing pipeline, occlusion support initially
Strip reflection from ray tracing shader spirv to deal with validation warnings
Don't use an array of vk descriptor types directly, this breaks with non-contiguous enum values which are common in extensions. Using a TMap from descriptor type to values instead.
Don't store vk types in the serialized shader header, translate to and from our own internal enum types to avoid similar non-contiguous value issues.
Re-enabled ray tracing compilation on windows desktop, explicitly disable runtime support using GRHISupportsRayTracing
Todo:
We need to deal with the lack of a 1:1 mapping between shader stages and frequencies for ray tracing hit groups. This is a one to many mapping which doesn't work with how most of the Vulkan RHI is authored. For now I'm assuming a hitgroup maps to a CHS.
Ray tracing shader descriptor allocation and pending state support. While we are serializing the descriptors for ray tracing shaders, we're not allocating or updating them yet which is the last large chunk needed to trace rays.
Fix spirv binary version mismatch validation error. This basically needs a local dxc modification which explicitly sets the spirv binary version to work around incorrect assuptions in dxc which is causing validation failures.
Add another local dxc modification to allow for arbirary struct size support using VK_EXT_scalar_block_layout for ray tracing shaders.
