Pull request description:

  This PR:

  - builds on #19991 and #19998
  - exposes peer networks via a new getpeerinfo `network` field ("ipv4", "ipv6", or "onion"), and adds functional tests
  - updates -netinfo to use getpeerinfo `network` rather than detecting the peer networks client-side
  - refactors -netinfo to easily add future networks
