ecore/input: attempt to more accurately handle multi-touch mouse-in events
when dealing with touch events, we should attempt to rely more on the hw event stream rather than synthesizing our own events with incorrect data. mouse in/out events don't usually provide device data, so we have no need to emit these events in the case of multi-touch event sequences Differential Revision: https://phab.enlightenment.org/D11205
