- members of FStaticMeshRayTracingProxy can point to either ray tracing specific mesh data or reuse the rendering LODs (in this initial CL only rendering LODs are supported).

- only create FRayTracingGeometry objects if ray tracing is enabled on static mesh, project and platform.

- don't modify DDC key based on cvar since it doesn't impact LOD generation since CL 18820056.
- removed bGenerateCoarseMeshStreamingLODs parameter from a few functions since it isn't used anymore.

Use FSignedDistanceFieldBuildSectionData when generating distance fields for Nanite meshes.
Context:
- Nanite meshes distance fields are generated using the original mesh data instead of the coarse representation generated by Nanite, however that code path was not checking section data such as blend mode, two sided, etc.
Fix:
- Modified FStaticMeshBuilder::BuildMeshVertexPositions(...) to also output a FStaticMeshSectionArray.
- Updated MeshRepresentation::SetupEmbreeScene(...) to check section flags when using SourceMeshData.IsValid() code path.
