Fix pg_upgrade to detect non-upgradable anyarray usages.

When we changed some built-in functions to use anycompatiblearray
instead of anyarray, we created a dump/restore hazard for user-defined
operators and aggregates relying on those functions: the user objects
have to be modified to change their signatures similarly.  This causes
pg_upgrade to fail partway through if the source installation contains
such objects.  We generally try to have pg_upgrade detect such hazards
and fail before it does anything exciting, so add logic to detect
this case too.

Back-patch to v14 where the change was made.
