fix(mdns): only advertise listening addresses matching the interface IP

[MatthiasvB]

When responding to mDNS queries, only advertise listening addresses whose IP matches the address family / interface the query arrived on, instead of advertising every listening address. Avoids announcing unreachable addresses.

Description

mDNS currently wildly reports all interface's addresses on all interfaces, which leads to mutiple issues:

Fixes #5995.
Fixes #5790.

There already is a PR, but it's been open for a long time and seems more complex: #6003

Notes & open questions

The fix seems smart and in the right place, but I lack complete overview over the crate, so some expert review should verify this is a good spot for the fix
