Extend PageIsVerified() to handle more custom options
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 routine that calls the
new extended routine with the set of options compatible with the
original version. Contrary to d401c576, a macro cannot be used as there
may be external code relying on the presence of the original routine.
This is applied down to 11, where this will be used by a follow-up
commit addressing a set of issues with page verification in base
backups.
