75a21c9bb9 ModelingTools: add support for creating Volumes directly from DrawPolygon, DrawRevolve, DrawPolyPath, and AddPrimitive, CombineMeshes, CutMeshWithMesh, PlaneCut, BaseCreateFromSelected Tools. Improve support for Editing volumes, eg handling mesh/volume interactions, and add configurable auto-simplification for volumes to avoid painful Editor hangs.
- Move ToolTarget implementations, DynamicMeshToVolume to ModelingComponentsEditorOnly module
- move VolumeToDynamicMesh, DynamicMeshProvider/Commiter interfaces to ModelingComponents module
- Add UCreateMeshObjectTypeProperties property set to expose mesh/volume options
- Add FCreateMeshObjectParams::TypeHintClass to allow AVolume type (or other UClass hints) to be passed to creation APIs
- Add UE::ToolTarget::ConfigureCreateMeshObjectParams() util function in ModelingToolTargetUtil, tries to determine output type in a FCreateMeshObjectParams based on input ToolTarget
- Add UEditorModelingObjectsCreationAPI::CreateVolume() implementation
- Add UEditorModelingObjectsCreationAPI::FilterMaterials() that strips out any internal materials and replaces with WorldGridMaterial. This occurs when (eg) subtracting a Volume from a StaticMesh, because the temporary volume mesh gets assigned internal materials, but the Tools don't know this. Use in EditorModelingObjectsCreationAPI when creating new objects. UStaticMeshComponentToolTarget also does this filtering in ::CommitMaterialSetUpdate().
- Add ::ComponentTypeSupportsCollision() function to ComponentCollisionUtil, use to avoid checks/ensures for Volume targets
- Add support for automatic mesh simplification in DynamicMeshToVolume. Add CVar to VolumeDynamicMeshToolTarget.h to control max triangle count (default 500). Apply auto-simplify when creating or updating an AVolume. This prevents the Editor from blocking for long periods on meshes that are too high-res for volumes (even 500 is quite high).
- DynamicMeshToVolume now emits polygroup-faces that contain holes (ie multiple boundary loops) as a set of triangles, rather than emitting separate overlapping faces for each boundary loop

51d4cb3f66 Fully deprecated old MeshDescription APIs.
Prepared direct attribute access for deprecation, preferring use of APIs to access static mesh attributes.
Fixed recently merged Enterprise code to comply with new APIs.
Changed all tools to use triangle-centric iteration where possible.
Added new MeshAttributeArray APIs for querying attribute flags, and added a new Mandatory flag.
Various bug fixes.
