- Add r.Shadow.DetectVertexShaderLayerAtRuntime to make it possible to force (for DX11/12/SM5/Vulkan) compilation of vslayer despite RHISupportsVertexShaderLayer being false.
- Set r.Shadow.DetectVertexShaderLayerAtRuntime in WindowsEngine.ini,WinGDKEngine.ini & LinuxEngine.ini.
- Add DoesRuntimeSupportOnePassPointLightShadows to determine support at runtime.
- Fix bug excluding Nanite meshes from DF shadows for local lights if VSM is enabled (now only affects directional lights).
- Add OnGetOnScreenMessages to enable modular generation of on-screen messages in the scene renderer (aimed at transient rendering processes).

AMD still has issues with SM6.6 but we can't wait on their fixes much longer.

Plumb through all required stage flags, access masks, layouts, renderpass attachments, etc for the VK_KHR_fragment_shading_rate extension.
Fix up logic used to gather VRS properties (tile sizes, data type/format).
Add templated version of VkFragmentShadingRateAttachmentInfo, attach to renderpasses where supported and when attachment provided.

Should use the provided shader platform when deciding which permutation to compile instead of relying on the global GRHISupportsWaveOperations
Enable wave operations for PCD3D_SM6 (part of ShaderModel 6.0)

- Add CVar (r.Vulkan.Allow64bitShaderAtomics) to forcefully disable 64bit image atomics. Currently defaults to 0 (until other components are in).
- Check driver version for Vulkan on NVIDIA, a fix was added for the 64bit image atomics that is required for Nanite. (currently Windows only, Linux TBD)

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.
