- Move UCreateMeshObjectTypeProperties to ModelingComponents and update all include sites
- Added Editor Modeling Mode settings to Enable/Disable showing DynamicMeshActor creation options, and select default mesh object type. Removed CVarEnableDynamicMeshActors.
- Added optional 'Auto' output mesh type to UCreateMeshObjectTypeProperties. This can be used in Tools that have input objects and want to allow optional conversion, but default to 'just use input mesh object type'.
- Added ConvertMeshesTool, this does in-place conversion between Mesh Object types for a set of selected objects (Duplicate tool can also do this, but only for a single object, and functionality is expected to further diverge)
- Added SplitMeshesTool, decomposes a mesh into parts and creates a new output object for each part
- CombineMeshesTool now supports variable output object type. Cleaned up internals.

- 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

[CL 16561742 by Ryan Schmidt in ue5-main branch]
- add new UModelingObjectsCreationAPI and associated data structures, provides abstract API for creating mesh and texture objects from Tools that is not specifically tied to StaticMesh Actors/Assets
- new helper functions in UE::Modeling:: namespace to simplify usage of an implementation of this API registered in a ContextObjectStore
- add new UEditorModelingObjectsCreationAPI implementation of above, supports hooks for higher level to provide custom paths
- add ModelingModeAssetUtils.h, provides several functions in UE::Modeling:: namespace to be used to implement those hooks (various existing path-determination code is moved here)
- ModelingToolsEditorMode now registers an instance of UEditorModelingObjectsCreationAPI in ContextObjectStore and connects up callbacks to these path functions
- AssetGenerationUtil functions and ModelingModeAssetAPI deleted
- All Tools that previously used IToolsContextAssetAPI updated to use this new system

IntervalGizmo is now just registered and unregistered as needed by the MeshSpaceDeformerTool, as this is the only place it is currently used.
Previous implementation in InteractiveGizmoManager is left intact as there are a few uses outside of MeshModelingTools that need to be cleaned up before it can be deleted.
UTransformGizmo now requires it's Builder to tell it which sub-gizmo identifier strings to pass to the GizmoManager to create axis/plane/rotation sub-gizmos (and the code that registers the Builder must then provide these strings). This cleans up previous explicit references to UInteractiveGizmoManager static strings from UTransformGizmo.
