- 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 UE::ToolTarget::CommitMaterialSetUpdate() and ::CommitDynamicMeshUpdate(). ::GetDynamicMeshCopy() can now return tangents if requested.
- Add IMeshDescriptionProvider::CalculateAutoGeneratedAttributes(). Default implementation does nothing, UStaticMeshComponentToolTarget implementation initializes auto-generated MeshDescription attributes. Used in ::GetDynamicMeshCopy() to get tangents (but requires a MeshDescription copy).
- Clean up handling of Tangents in Simple/OctreeDynamicMeshComponent. Add local MakeTangentsFunc() to generate the Tangents lambda, handle different cases and no-tangents fallbacks consistently.
- UDynamicMesh: add optional info arguments to EditMesh() and ChangeInfo struct. Add support for deferring change events from Edit funcs.
- Remove UBaseDynamicMeshComponent::InitializeMesh(), ::Bake() APIs, and add ::SetMesh(). Implement in Simple/Octree implementations, update all Tools that used those APIs.
- Add USimpleDynamicMeshComponent::ProcessMesh(), EditMesh(). These are now the preferred ways to read/write mesh.
- Update USimpleDynamicMeshComponent tangents handling. Externally-computed tangents are now taken directly from the FDynamicMesh3 attribute set. Autogenerated tangents are still computed and stored in an internal FMeshTangentsf, but this is no longer exposed for external updates.
- Remove UPreviewMesh pass-through functions for Tangents access, InitializeMesh() and Bake(). Add ProcessMesh()
- Update all affected Tools. In most cases these Tools have also been converted to use ModelingToolTargetUtil functions, instead of direct ToolTarget interface casting.

[CL 16650666 by Ryan Schmidt in ue5-main branch]
Add support for submitting multiple UV channels to render buffers in UBaseDynamicMeshSceneProxy and USimpleDynamicMeshSceneProxy (currently not supported if there is a mesh decomposition, and not supported in fast UV updates).
Add support for visualizing different UV channels in UExistingMeshMaterialProperties.
Add UMeshUVChannelProperties property set for selecting from available UV channels.
Add support for arbitrary UV channels in ParameterizeMeshTool and UVLayoutTool/Op.
