* FRayTracingGeometry can now be initialized in one of 3 states: Rendering, StreamingDestination and StreamingSource:
- Rendering: buffer and shader parameters are created.
- StreamingSource: only buffer is created
- StreamingDestination: nothing is created.
* Life of a streamed FRayTracingGeometry looks as follows:
1. Created with StreamingDestination
2. TStaticMeshStreamIn_IO::DoCreateBuffers creates a temporary FRayTracingGeometry (StreamingSource type) from CPU data.
3. FStaticMeshStreamIn::DoFinishUpdate: schedules a copy of RayTracingGeometryRHI on RHI thread (InitRHIForStreaming) and enqueues a render command to update hit group parameters and schedules a build if needed (RequestBuildIfNeeded).
4. Temporary FRayTracingGeometry is released.
5. When no longer needed the original FRayTracingGeometry is released (ReleaseRHIForStreaming)
* Added code to SetInitializer and Swap FRHIRayTracingGeometry that is needed for RHITransferRayTracingGeometryUnderlyingResource.

- For example, if it was created using ERTAccelerationStructureBuildPriority::Skip.
- Fix assert for skinned meshes using WorldPositionOffset.

- A ray tracing geometry RHI object replaces the TResourceArray allowing platform RHIs to access offline cooked BVH data from GPU memory.
- Removed "r.SkeletalMesh.PostbuildMeshData" cvar as it wasn't correctly versioned. Disabling skeletal mesh BVH cook should be done in the platform cooker module so to affect DDC key correctly.
Fix crash in LumenHardwareRayTracingMaterials.cpp when using -onethread mode
- Renderer code was attempting to allocate memory on the RHI command list, but this is not allowed when RHI bypass is enabled.
