Add a new reloption, user_catalog_table.

When this reloption is set and wal_level=logical is configured,
we'll record the CIDs stamped by inserts, updates, and deletes to
the table just as we would for an actual catalog table.  This will
allow logical decoding to use historical MVCC snapshots to access
such tables just as they access ordinary catalog tables.

Replication solutions built around the logical decoding machinery
will likely need to set this operation for their configuration
tables; it might also be needed by extensions which perform table
access in their output functions.
