USD import: replace deprecated shape import code.
The static functions GetMeshPoints() and GetTopology()
have been removed from the adapter classes in USD 22.11.
In anticipation of this change, the code was updated to
call the corresponding virtual functions instead.
Change authored by Charles Wardlaw.
