Refactor duplicate code into DeconstructFkConstraintRow
My commit 3de241dba86f introduced some code (in tablecmds.c) to obtain
data from a pg_constraint row for a foreign key, that already existed in
ri_triggers.c. Split it out into its own routine in pg_constraint.c,
where it naturally belongs.
No functional code changes, only code movement.
Backpatch to pg11, because a future bugfix is simpler after this.
