- 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.

- ADynamicMeshActor type has a UDynamicMeshComponent subobject (similar to StaticMeshActor)
- Add IPersistentDynamicMeshSource, a ToolTarget Interface for accessing a UDynamicMesh
- Add UDynamicMeshComponentToolTarget, a UToolTarget implementing the above as well as various standard interfaces, to allow Tools to operate on an external DynamicMeshComponent
- Update UE::ToolTarget:: helper functions that get/commit via DynamicMesh to handle IPersistentDynamicMeshSource directly, instead of going via existing MeshDescription/DynamicMesh interfaces. Add UE::ToolTarget::SetSourceObjectVisible() helper function.
- Add support for creating DynamicMeshActors in UCreateMeshObjectTypeProperties and UEditorModelingObjectsCreationAPI
- register UDynamicMeshComponentToolTargetFactory in ModelingToolsEditorMode
- Rename existing internal ADynamicMeshActor to AOldDynamicMeshActor. Does not appear to be in use and will be removed in a future CL.

Exclude from the mesh generation all mesh sections that are using materials for which the material domain isn't "Surface" (ex: decals)
Those will still be rendered properly in the material baking phase.
Prevent black patches in places where decals aren't resting on surfaces

UMeshElementsVisualizer::SetMeshAccessFunction() now takes a TFunction with a TFunctionRef argument, instead of with a FDynamicMesh3* argument. This allows the UMeshElementsVisualizer to access the target mesh via the ProcessMesh()-style call on a UPreviewMesh, UDynamicMesh, etc, rather than receiving direct pointer access. See UWeldMeshEdgesTool::Setup() for example usage.
Add UMeshOpPreviewWithBackgroundCompute::ProcessCurrentMesh(), which forwards to the embedded UPreviewMesh::ProcessMesh() (which can be used with the above)
Add UE::ToolTarget::GetMeshDescriptionCopy() to ModelingToolTargetUtil, similar to existing DynamicMesh variant that will auto-compute tangents if necessary.

- 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.
