useful for RVT on mobile platforms, to save the cost of runtime compression

- Refactored RDG to support free-threaded execution of passes.
- Refactored renderer to use specific RHI command list variants in pass lambda. Immediate command list passes are forced to stay on the render thread, while other variants can be parallelized.

Renamed FDataDrivenPlatformInfo::AudioCompressionSettingsIniSectionName to TargetSettingsIniSectionName. It's now used to populate PlatformMask at runtime, to make sure that it matches between cook and runtime. Before it was possible to cook with e.g. GRayTracingPlaformMask=0, but then the cooked game would run with GRayTracingPlaformMask=1.

- Uses the InstanceCullingLoadBalancer to pre-distribute the work on the CPU to ensure even load.
- Make instance culling use the instance data offset in MDC instead of translating primitive IDs.
- Track single-instance draws separately from instanced to optimize handling (disable culling for single-instance primitives).

2. Add an option to use high quality BRDF on mobile as the same with PC.
3. Fallback to default light shading model if it is not supported on mobile.
4. Use EnvBrdf for mobile deferred lighting pass.

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.

FMaterialRenderProxy doesn't appear to know which FScene it belongs to, so I had to go through the global render module and flag all scenes instead
