- 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

In some edge configurations two 'terminator' vertices (at the end of open bevel edge paths) are directly connected by a non-bevel edge that we will "open", and this creates a quad-shaped hole instead of a triangle-shaped hole (which was already handled). Detecting this case will arise is simpler before we change the topology, so it is done in BuildVertexSets(), stored in FBevelVertex::ConnectedBevelVertex, and used during mesh generation to call new AppendTerminatorVertexPairQuad function.
In BuildTerminatorVertex(), the search for a terminator split-edge may fail if the filtered triangle list ends up non-contiguous, preventing the vertex from being beveled (ie it is "stuck"). Code was added to both handle that case, and also try to force the list to stay contiguous.

(+ for code that was passing false then manually applying the same logic, remove the extra reverse orientation logic)

ModelingTools: add support for writing to selected group layer, as well as new group layer, in ConvertToPolygonsTool (GrpGen in UI). Also add support for setting groups from existing layer, which (combined) allows copying groups between layers, duplicating existing layer, and so on.

GeometrySelectionUtil: add FindByTopologyID function, to search a Selection for selected element with matching TopologyID but ignoring GeometryID. Update FGeometryScriptMeshSelection::CombineSelectionInPlace() to use this, as it was not properly combining Polygroup selections.
