Michael Paquier a977e419ee Refactor ReadMultiXactCounts() into GetMultiXactInfo()
This provides a single entry point to access some information about the
state of MultiXacts, able to return some data about multixacts offsets
and counts.  Originally this function was only able to return some
information about the number of multixacts and multixact members,
extended here to provide some data about the oldest multixact ID in use
and the oldest offset, if known.

This change has been proposed in a patch that aims at providing more
monitoring capabilities for multixacts, and it is useful on its own.
GetMultiXactInfo() is added to multixact.h, becoming available for
out-of-core code.

Extracted from a larger patch by the same author.
