udevadm: trigger: implement --initialized-match/nomatch arguments
systemd-udev-trigger.service by default triggeres all devices regardless
of whether they were already recognized by systemd-udevd.
There are machines (especially in embedded environments) where
systemd-udev-trigger.service is configured to run at a later stage of
the boot sequence, which can lead to quite a lot of devices being
triggered although they were already recognized by systemd-udevd.
Re-triggering a lot of devices is a relatively expensive operation and
therefore should be avoided if unnecessary.
Therefore this patch introduces --initialized-nomatch, which filters out
devices that are already present in the udev database. For consistance
reasons --initialized-match is implemented as well, which filters out devices
that are *not* already present in the udev database.
Replaces #19949.
