udevadm: allow to specify device by device ID

udevadm: allow to specify device by device ID

We have already exposed device ID in the output of device ID in J
fields. Also sd_device_get_device_id() and sd_device_new_from_device_id()
are already public. Hence, making udevadm accept device IDs may be
useful.

With this change, as we save several data in /run/udev with device ID,
we can call udevadm something like the following:
```
udevadm info $(ls /run/udev/tags/uaccess)
```
Then, we can show all devices that has uaccess tag.
