- create a new MeshTopologySelector base class. The existing GroupTopologySelector class now inherits from it, as does a new BoundarySelector class
- likewise, create a new MeshTopologySelectionMehchanic base class and have (existing) PolygonSelectionMechanic and (new) BoundarySelectionMechanic inherit from it
- the new Boundary classes use FMeshBoundary loops to define selectable loops rather than FGroupTopology
HoleFillTool:
- change to using BoundarySelectionMechanic instead of GroupTopologySelector
Misc:
- allow FMeshBoundaryLoops to fail untangling a loop with bowties but still continue processing other loops

ToolsFramework:
add UInteractiveCommand and UInteractiveCommandArguments types, base classes for 'interactive commands' which are intended to be used for atomic actions, ie stateless, no user interaction, etc
ModelingComponents:
add UGeometrySelectionEditCommand/Arguments, this is a UInteractiveCommand that uses a FGeometrySelection as an argument
add UGeometrySelectionManager::CanExecuteSelectionCommand() and ExecuteSelectionCommand()
MeshModelingTools:
add UDeleteGeometrySelectionCommand, deletes selected mesh geometry by converting input selection to list of triangles
ModelingToolsEditorMode:
add Delete command to ModelingMode and UI. ModelingToolsEditorMode currently is keeping active command set alive via new UModelingToolsEditorMode::ModelingModeCommands member.

GeometryCore: Add bClearExisting option to FDynamicMeshAttributeSet::EnableMatchingAttributes(). Default true is old behavior. New behavior, when false, is to preserve existing attribute set counts/values. Also now copying group and weight layer names if not set.
ModelingTools: CombineMeshesTool now uses EnableMatchingAttributes instead of only explicitly matching UV layers, so group and weight layers are copied properly to duplicates
MeshConversion: DynamicMeshToMeshDescription now generates unique names in ConvertPolygroupLayers and ConvertWeightLayers. Previously if multiple attribs had the same name (eg NAME_None), output MeshDescription would only have a single attrib w/ that name
