Bugzilla #5120, #7246: In CW's GC ops, validate the backing GC against the
backing drawable if the serial numbers differ. Fixes crash in XAA which occurred when the DDX bumped the serial number on the backing drawable and expected it to get re-validated, and we didn't because the wrapped drawable hadn't been bumped.
