modules: openthread: platform: mdns_socket: Update AIL address monitor

This commit improves AIL address monitoring; Associated function will be
called after OpenThread mDNS module starts platform code by
'otPlatMdnsSetListeningEnabled`.
A new flag, `mdns_socket_is_enabled` has been added to support this new
logic.
