pgstattuple: Have pgstattuple_approx accept TOAST tables
TOAST tables have a visibility map and a free space map, so they can
be supported by pgstattuple_approx just fine.
Add test cases to show how various pgstattuple functions accept TOAST
tables. Also add similar tests to pg_visibility, which already
accepted TOAST tables correctly but had no test coverage for them.
