* Split IsRayTracingEnabled() into 2 parts: IsRayTracingEnabled() which can be changed at runtime and IsRayTracingAllowed() for checking if ray tracing can be enabled.
* r.Raytracing can now have following values: 0 - disabled, 1 - enabled all the time, 2 - enabled dynamic
* When ray tracing is dynamic, RayTracingGeometryManager will collect all FRayTracingGeometry and allocate/release RHI objects as needed depending on if ray tracing is enabled or not.
* Ray tracing can be switched on/off with r.Raytracing.Enable (default is 1).
* Add support to most features used in CitySample/Lyra for switching ray tracing at runtime.
* TODO: Hair geometries are not yet released.

- Clean up temporary fix
- Modify UpdatePreviewPlatforms to only restrict DDSPI properties and not enable them if the preview platform doesn't have them on

This change includes significant refactor work performed in //UE5/Dev-ParallelRendering. A brief summary of the work is as follows:
Refactored RHI command lists
- Removal of the "immediate" async compute command list
- Introduced an "active pipe" on each command list, allowing RHICmdLists to record work for either graphics or async compute. Pipes can be selected using the SwitchPipeline() function, or the FRHICommandListScopedPipeline helper.
- New explicit command list submission RHI API (RHIFinalizeContext, RHISubmitCommandLists). The IRHICommandContextContainer type has been removed.
- Explicit GPU submission is automatically appended to the immediate command list when it is dispatched to the RHI thread.
Platform RHI implementations
- The new submission API has been implemented across all platforms. Some platforms required a significant refactor.

No functional changes, just reflecting the name of the CVar itself (r.RayTracing.RequireSM6).

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)
