Evas events: Split pointer events

Evas events: Split pointer events

This is going back to the same idea as legacy. We will have
events such as:
- move
- down
- up
- in
- out
- wheel
- cancel ("new" - very rare)

Now the question is whether/how we should divide "multi" events
which start from the 2nd finger from standard mouse events. The first
multitouch finger should by default look like a mouse event.
