clutter: Check updated devices with the current clip

Browse Source 
We do check the clip area as an optimization to know which input devices
might need updating state after a relayout (Assuming that if a device is
under a non-painted area, it's actor beneath didn't change).

Use the clip region for this, and drop the last usage of the clip region
bounds.
