Allow NOT VALID foreign key constraints on partitioned tables
This feature was intentionally omitted when FKs were first implemented
for partitioned tables, and had been requested a few times; the
usefulness is clear.
Validation can happen for each partition individually, which is useful
to contain the number of locks held and the duration; or it can be
executed for the partitioning hierarchy as a single command, which
validates all child constraints that haven't been validated already.
This is also useful to implement NOT ENFORCED constraints on top.
