A new lit vertex color material is added and used if the ModelingComponents module is loaded (to avoid adding a new engine material, if only GeometryFramework is loaded, then the engine-default vertex color material is used). This class-wide vertex color material can be overridden via UBaseDynamicMeshComponent::SetDefaultVertexColorMaterial()
Facet Normals / Flat Shading is now separately configurable, this overrides the normals at the vertexbuffer setup level, so it works independently of material.
Support also added for configuring the wireframe material used for BaseDynamicMeshComponent, and also for setting the wireframe color.

[CL 18821641 by andrew davidson in ue5-main branch]
- add FRayTracingGeometry structures to FMeshRenderBufferSet for primary and secondary triangle indices
- add UpdateRaytracingGeometryIfEnabled() function which rebuilds these raytracing data structures. This does a full rebuild, not clear if any kind of incremental update is possible currently, to revisit in future.
- call the above in the various places where we modify the existing index/vertex buffers.
- add UPrimitiveComponent::GetDynamicRayTracingInstances() implementation, mirrors GetDynamicMeshElements() implementation, uses new DrawRayTracingBatch() function
