pg_upgrade: prevent automatic oid assignment

Prevent automatic oid assignment when in binary upgrade mode. Also
throw an error when contrib/pg_upgrade_support functions are called when
not in binary upgrade mode.

This prevent automatically-assigned oids from conflicting with later
pre-assigned oids coming from the old cluster. It also makes sure oids
are preserved in call important cases.
