apicheck: Allow safe addition and removal of final qualifier.
Split the CHANGED_FINAL error into ADDED_FINAL,
ADDED_FINAL_UNINSTANTIABLE and REMOVED_FINAL so that the
API check scripts can more precisely target policy around
changes to the final qualifier.
ADDED_FINAL_UNINSTANTIABLE covers the case of a class
that has become final but that was previously not
instantiable. This change is safe since applications could
not have declared subclasses of their own.
