Pass down table relation into more index relation functions
This is done in preparation for logical decoding on standby, which needs to include whether visibility affecting WAL records are about a (user) catalog table. Which is only known for the table, not the indexes. It's also nice to be able to pass the heap relation to GlobalVisTestFor() in vacuumRedirectAndPlaceholder().
