ryan schmidt c41af3c4c7 CombineMeshInstances: Add support for 2D retriangulation of planar areas, after coplanar face merging. This can further reduce triangle count as the planar-simplification applied after coplanar merging often cannot remove vertices on region borders, limiting it's effectiveness. ...

Also tweaked geometric tolerances recently added to RemoveHiddenFaces_ExteriorVisibilit() as they seem to be too aggressive (need to add real-world dimensions here).
Updated internal usage to enable this new capability

IGeometryProcessingInterfacesModule.h

Add initial version of new CombineMeshInstances geometry processing Modular Feature and initial implementation. This modular feature is used to construct a 'merged' mesh for a large number of input mesh instances, with the idea that simplifying or abstracting each instanced base mesh (ie unique "part") before appending will produce a better (ie more accurate + lower polycount) combined mesh than trying to combine first and then do standard simplification technqiues on the merged mesh. Currently only per-part simplification and fitting oriented boxes is supported. This is a functional checkpoint of work in progress.
