With this, we have separate functions to add validation requests to ALTER TABLE's phase 3 queue for check and foreign key constraints, which allows reusing them in future commits -- particularly this will allow us to perform validation of invalid foreign key constraints in partitioned tables. We could have let the check constraint code alone since we don't need to reuse that for anything at this point, but it seems cleaner and more consistent to do both at the same time.
