- 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
