Fix detach of a partition that has a toplevel FK to a partitioned table
In common cases, foreign keys are defined on the toplevel partitioned
table; but if instead one is defined on a partition and references a
partitioned table, and the referencing partition is detached, we would
examine the pg_constraint row on the partition being detached, and fail
to realize that the sub-constraints must be left alone.  This causes the
ALTER TABLE DETACH process to fail with

 ERROR:  could not find ON INSERT check triggers of foreign key constraint NNN

This is similar but not quite the same as what was fixed by
53af9491a0.  This bug doesn't affect branches earlier than 15, because
the detach procedure was different there, so we only backpatch down to
15.

Fix by skipping such modifying constraints that are children of other
constraints being detached.
