resolved: add bus API for configuring per-link DNS settings

This is useful for alternative network management solutions (such as NetworkManager) to push DNS configuration data
into resolved.

The calls will fail should networkd already have taken possesion of a link, so that the bus API is only available if
we don't get the data from networkd.
