Grants and revokes where not propagated to compressed hypertables, if the hypertable had a compressed hypertable, meaning that `pg_dump` and `pg_restore` would not be able to dump nor restore the compressed part of a hypertable unless they were owners and/or was a superuser. This commit fixes this by propagating grants and revokes on a hypertable to the associated compressed hypertable, if one exists, which will then include the compressed hypertable and the associated chunks in the grant and revoke execution. It also adds code to fix the permissions of compressed hypertables and all associated chunks in an update and adds an update test to check that the permissions match. Fixes #3209
