The new function resolve an address via DNS, first by using
systemd-resolved (disabling synthesized results) and then by spawning
the daemon helper.
Trying systemd-resolved via D-Bus before spawning the helper is
important to get a correct result. Suppose that resolv.conf points to
the local stub listener at 127.0.0.53; if NM only spawns the helper,
the helper will query the local systemd-resolved which could return a
synthesized result.
Therefore, we first query systemd-resolved with NO_SYNTHESIZE and
then, in case of error, we spawn the helper.
