[schema] Implement security for top level types (ArchiveTransfer, ArchiveUnit, AuthorityRecord and ConceptScheme). For now, we only need to setup ConceptScheme compound security since it's not done yet by the skos cube, while it is in eac and seda cubes. We need to follow a change in the seda cube to get tests to green. Closes #16684441
