m/n/c/network: implement ARP announcements

This implements ARP announcements in the Metropolis network stack.
Its intent is to help IP stacks on the same broadcast domain to update
their ARP entries once a Metropolis network stack comes up.
The format of the ARP packets is chosen to bypass most EVPN ARP
suppression mechanisms to ensure this also works with these systems.
