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.

- Add new UModelingComponentsSettings which has settings for in-tool preview mesh rendering and emitted new mesh objects
- Add ToolSetupUtil::ApplyRenderingConfigurationToPreview() utility functions, most Tools now call this function to configure UPreviewMesh/DynamicMeshComponents they create for mesh editing preview rendering (uses Settings to make setup decisions like RT on/off)
- add PreviewMesh::NotifyWorldPathTracedOutputInvalidated(), forces invalidation of current path tracing result, call from various PreviewMesh internal functions
- UCreateMeshObjectTypeProperties::ConfigureCreateMeshObjectParams() now configures new-mesh-object parameters with RT and Collision from UModelingComponentsSettings
- DynamicMeshComponent now defaults to raytracing-enabled, usage in Editor is controlled by above settings

- 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

- UDynamicMesh Reset() functions now return themselves, configured as BP output pin, helps to make BP wiring cleaner
- added DynamicMeshComponent::ConfigureMaterialSet() and ::ValidateMaterials(), to allow material set to be updated from BP
- added BaseDynamicMeshComponent::SetNumMaterials() to support above
