api_facts - also report interfaces that are inferred only by reference by IP addresses.
RouterOS's APIs have IPv4 and IPv6 addresses point at interfaces by their name, which can
change over time and in-between API calls, such that interfaces may have been enumerated
under another name, or not at all (for example when removed). Such interfaces are now reported
under their new or temporary name and with a synthetic ``type`` property set to differentiate
the more likely and positively confirmed removal case (with ``type: "ansible:unknown"``) from
the unlikely and probably transient naming mismatch (with ``type: "ansible:mismatch"``).
Previously, the api_facts module would have crashed with a ``KeyError`` exception
(https://github.com/ansible-collections/community.routeros/pull/391).
