Made GeometryCollection::AppendSkeletalMesh more generic so it can take just a FManagedArrayCollection.
- Added a static version of FGeometryCollection::UpdateBoundingBox
- Added a static version of FGeometryCollection::ReindexMaterials
- Added Interface for standard attribute creation

- make material duplication for internal materials optional
- ask if user wants to split the mesh by connected component
+ implement the connected component split on the mesh description as part of the conversion, so we can do it before we've thrown out the mesh topology (geometry collection is a rendering rep that can't represent mesh topology; it splits at every UV seam and sharp edge)
