The engine uses GRayTracingPlaformMask to compute ShouldCompilePermutation() for shaders. This is filled based on platform settings and capabilities when running the editor. When running a standalone game, the mask is filled purely based on whether ray tracing is enabled for the project (r.RayTracing) and the current runtime environment supports it (GRHISupportsRayTracing).
The new CVar is meant to be consistent between the cook time and run time. This is achieved by setting GRHISupportsRayTracing=false when running on SM5 if r.RayTracing.RequireSM6 is 1.

r.Mobile.ShadingModelsMask can be used to mask out specific shading models on mobile platforms.
Masked shading models will fallback to DefaultLit

- Saves ~0.3ms on PS4/XB1 (Dynres = 100%).
-Add possibility to disable grass velocity output when WPO velocity is enable (only effective when r.velocity.enablevertexdeformation != 0 and r.OptimizedWPO = true)

* Add ITargetPlatform::GetRayTracingShaderFormats(), with default implementation that falls back to GetAllTargetedShaderFormats() if HWRT is enabled for a platform
* Override GetRayTracingShaderFormats() for TGenericWindowsTargetPlatform to return only enabled D3D12 and VK shader formats (excluding D3D11)
* Use GetRayTracingShaderFormat() and UsesRayTracing() to configure GRayTracingPlaformMask (the mask contains one bit per shader platform)
Previously all bits of GRayTracingPlaformMask were set if project uses ray tracing, then shader platform bits were disabled for all possible shader formats for platforms that don't support ray tracing.
If SM5 was disabled for D3D12, ray tracing shaders would still get compiled for it because the corresponding bit was still set in GRayTracingPlaformMask.
With this change, SM5 bit will no longer be set in GRayTracingPlaformMask in the editor if it is disabled for D3D12 RHI for the project, so ray tracing shaders won't be compiled.
When running a packaged build, GRayTracingPlaformMask is now set to 0 or 1 based on global project setting (r.RayTracing) and whether the current machine+RHI supports ray tracing.

This resubmits the following original changelists (with fixes).
Original CL Desc for CL20737284 -----------------------------------------------------------------
Add a version of UseVirtualTexturing() that takes a shader platform.
A future goal is to deprecate the version that takes a feature level.
Original CL Desc for CL20738687 -----------------------------------------------------------------
Virtual texturing forces depth pass on.
This fixes bug when using any masked materials that sample VT.

2.Uses the same shading models and dynamic lightings code path on desktop.
3.Remove the division of PI on mobile directional light's color in C++ to line up with desktop in shaders.
