Fix flakiness in the pg_visibility VM-only vacuum test by using a temporary table.
The test relies on VACUUM being able to mark a page all-visible, but this can fail when autovacuum in other sessions prevents the visibility horizon from advancing. Making the test table temporary isolates its horizon from other sessions, including catalog table vacuums, ensuring reliable test behavior.
