ecore_drm: Handle wheel scrolling separately from finger scrolling
Wheels are discrete and scroll in clicks, fingers are continuous and scroll
in fractional pixels.
This change causes wheel based scrolling to be returned in "clicks"
instead of "degrees" - allowing us to roll a single menu item with a click.
It also will allow us to reduce the speed of two finger scrolling without
messing up the speed of wheel scrolling.
