Currently, `PublishMultiple()` on the lease manager, which updates multiple table descriptors in a single transaction as part of a schema change, updates each table descriptor independently of the others. There was a bug where if the call to `PublishMultiple()` to add FKs and backreferences was retried (e.g., if there was a crash after this step but before the finalization of the schema change), we would correctly avoid re-adding the reference to the table, but the backreferences would be incorrectly added a second time. This change updates the interface of `PublishMultiple()`: There's now a single update closure which has access to a map of all table descriptors being modified. Backreferences are now only installed if the forward reference was also installed. Release note: None

Within backfill, do not add the unvalidated constraints to the queues for validating. Release note (sql change): Support NOT VALID for check constraints, which supports not checking constraints for existing rows.
