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

Adding shader symbol export path override cvar. This cvar supports specifying the shader platform name via "{Platform}".
Adding Luke's change for having build machine specific shader configs.

--
Repacked prim data (removes 8x float32)
Implemented builder pattern for primitive uniform shader parameters
Various cleanup, optimizations, improvements - all forming a basis for subsequent refactors and optimizations
Derive calculations like lighting channel mask, per object gbuffer data, and determinant sign bit on the GPU now, instead of wasting buffer space on it.
Removed LPV bias (unused)
