Add display transform to MotionEvent for raw coords

Since input now works in display coordinates, we need to include the
display projection with MotionEvent so that the getRaw API can continue
to report logical display coordinates.

It is also important to highlight the difference in the coordinate
systems used by regular input windows and input monitors. MotionEvents
coming from input monitors will always report values in unrotated
logical display coordinates, because we do not yet have an API to report
unrotated values in MotionEvents.
