Extend PageIsVerified() to handle more custom options

Browse Source 
This is useful for checks of relation pages without having to load the
pages into the shared buffers, and two cases can make use of that: page
verification in base backups and the online, lock-safe, flavor.

Compatibility is kept with past versions using a macro that calls the
new extended routine with the set of options compatible with the
original version.

Extracted from a larger patch by the same author.
