Fix T53491: Absolute tablet motion detection fails

When using a tablet, detecting absolute motion only worked
when activating a tool with the tablet.

Pressing Enter to run a tool for e.g. would use relative motion.

Now store is_motion_absolute in the event,
set for new events based on the most recent motion events.
