Parallel pg_restore has always supposed that ACL items for different
objects are independent and can be restored in parallel without
conflicts.  However, there is one case where this fails: because
REVOKE on a table is defined to also revoke the privilege(s) at
column level, we can't restore per-column ACLs till after we restore
any table-level privileges on their table.  Failure to honor this
restriction can lead to "tuple concurrently updated" errors during
parallel restore, or even to the per-column ACLs silently disappearing
because the table-level REVOKE is executed afterwards.

To fix, add a dependency from each column-level ACL item to its table's
ACL item, if there is one.  Note that this doesn't fix the hazard
for pre-existing archive files, only for ones made with a corrected
pg_dump.  Given that the bug's been there quite awhile without
field reports, I think this is acceptable.

This requires changing the API of pg_dump's dumpACL() function.
To keep its argument list from getting even longer, I removed the
"CatalogId objCatId" argument, which has been unused for ages.

Per report from Justin Pryzby.  Back-patch to all supported branches.
