Define MXID acronym in documentation

Hi,

I noticed that while XID (Transaction ID) is properly defined as an
acronym in the PostgreSQL documentation, MXID (Multixact ID) is used
without a formal definition.

This patch adds an entry for MXID to acronyms.sgml with a link to the
"Multixacts and Wraparound" section, and introduces the acronym in
maintenance.sgml alongside the existing "Multixact IDs" term, following
the same pattern used for XID.

Good find, pushed. Thanks for your contribution!

Thank you for pushing this.

Let me suggest one more small fix.

Since the preceding word is plural, the acronym should probably be
pluralized too: (<acronym>MXID</acronym>s) rather than
(<acronym>MXID</acronym>).

This matches existing conventions elsewhere in the docs, e.g. MCVs
(most common values) and MCFs (most common frequencies) in
planstats.sgml.
