Historically, the "dump" component of the namespace has been used to decide if the objects inside of the namespace should be dumped also. Given that "dump" is now a bitmask and may be partial, and we may want to dump out all components of the namespace object but only some of the components of objects contained in the namespace, create a "dump_contains" bitmask which will represent what components of the objects inside of a namespace should be dumped out. No behavior change here, but in preparation for a change where we will dump out just the ACLs of objects in pg_catalog, but we might not dump out the ACL of the pg_catalog namespace itself (for instance, when it hasn't been changed from the value set at initdb time).
