rpc: Add listen address to incoming connections in getpeerinfo

This adds the listening address on which incoming connections were received to the
CNode and CNodeStats structures.

The address is reported in getpeerinfo.

This can be useful for distinguishing connections received on different listening ports
(e.g. when using a different listening port for Tor hidden service connections)
or different networks.

This is a backport of Core PR10478

Depends on D1750 and D1756
