Subject: wireguard: T2206: split endpoint node into address and port

WireGuard has been the only subsystem combining a remote ip address and a
remote port number into a single node. This is bad as there is no possiblity
for the XML based input validation for IP address and port numbers.

That's the reason the peer endpoint node goets migrated into a peer address
and a peer port node utilizing the embedded syntax node checking for IP
addresses and port ranges.
