Fix misbehavior of DROP OWNED BY with duplicate polroles entries.
Ordinarily, a pg_policy.polroles array wouldn't list the same role
more than once; but CREATE POLICY does not prevent that. If we
perform DROP OWNED BY on a role that is listed more than once,
RemoveRoleFromObjectPolicy either suffered an assertion failure
or encountered a tuple-updated-by-self error. Rewrite it to cope
correctly with duplicate entries, and add a CommandCounterIncrement
call to prevent the other problem.
Per discussion, there's other cleanup that ought to happen here,
but this seems like the minimum essential fix.
Per bug #17062 from Alexander Lakhin. It's been broken all along,
so back-patch to all supported branches.
