MotionEvent: Transform mouse cursor position 

When calling MotionEvent::applyTransform, the x/y coordinates for all
PointerCoords are transformed accordingly. When this happens, we also
need to transform the mouse cursor position.

Bug: 179274888
Test: atest InputShellCommandTest (when the display is rotated to
different orientations)
