Use schema._copy_expression() fully in column collection constraints

Fixed issue where using :meth:`_schema.Table.to_metadata` (called
:meth:`_schema.Table.tometadata` in 1.3) in conjunction with a PostgreSQL
:class:`_postgresql.ExcludeConstraint` that made use of ad-hoc column
expressions would fail to copy correctly.

Fixes: #5850
