ryan schmidt 177f9e073c ModelingTools: add support for Mesh Selection to Generate Polygroups / Convert To Polygons Tool. ...

Base class is changed to USingleTargetWithSelectionTool.
When selection is provided, a UPreviewMesh for the unselected area is created and used.
A FSharedConstDynamicMesh3 is used to wrap either the original mesh or the selected submesh, and passed to the Operator (which also now takes a FSharedConstDynamicMesh3)
On shutdown, modified submesh is re-integrated into original mesh (in this case a trivial group copy suffices) and a new selection is emitted
