- Refactor recompute-UVs-for-groups/islands out of ParameterizeMeshOp/Tool into RecomputeUVsOp/Tool. RecomputeUVsTool supports selection of active PolygroupLayer when applicable. Add support for auto-repacking.
- Clean up ParameterizeMeshOp/Tool, remove functionality related to recomputation that was moved to Recompute tool, add separate property sets for UVAtlas and XAtlas
- Add FDynamicMeshUVEditor::QuickPack() function to compute UV layout
- Add support for Polygroup Layer selection in SetCollisionGeometryTool, if only one source object is in use

- 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

ModelingTools: Replace local code in UVProjectionOp with calls to FDynamicMeshUVEditor. Major rewrite of UVProjectionTool to support ExpMap projection, improve property handling, support world-space dimensions, support re-using previous projection to simplify world-space tiling, support input selections coming from PolyEdit/TriEdit, support ctrl+click and ctrl+shift+click interactions to reposition projection primitive.

- add scalar damping to vertex projection and normal fitting
- detect areas that cover holes in the target mesh and don't project in those regions
- expose smoothing parameters for these areas

Add insights profiling tags to RemeshMeshOp and FRemesher. Small optimizations to FRemesher::ProcessEdge(), which has surprising overhead for no-ops (ie edge is not modified).
Add FUniqueIndexSet, alternative to a TSet for constructing list of unique indices (eg when finding set of one-ring tris of a list of vertices). Generally more efficient, particularly for large sets.
Improve FSubRegionRemesher. Make VertexROI private, provide accessors and update usage sites. Optimize InitializeFromVertexROI(), which is an expensive part of dynamic mesh sculpting. Make FullSmoothPass_Buffer() compute in parallel.
ModelingTools:
Major refactor of DynamicMeshSculptTool to improve performance (2-4x improvement on large brush sizes on 1m triangle mesh). A single FSubRegionRemesher is now created and maintained for entire brush stroke, rather than recreating every stamp. This avoids the high cost of initialzing full-mesh constraint set, and allows re-use of various allocated memory buffers. Reorganize major sub-steps computed in a single brush-stamp tick to allow Async computation where possible. Replace some ROI TSets with FUniqueIndexSet. Instrument for Insights, remove old cycle counting.
