This prevents the firstFound device, or any device detected by UdevEnumerate::find that is not from the same seat kwin is running under, from being handled

- R108:99376d38f69f: udev: Only handle devices from the current seat
made sure that kwin starts on a default udev (assuming a blank ID_SEAT attribute on a device means the device is on seat0)
added /dev/dri/card1 to seat1 and /dev/dri/card0 to seat0.
Start kwin with the drm-backend on seat0 and seat1, and make sure it starts on both instances
