Updated MotionEvent to use Transform
Updated MotionEvent to use Transform instead of offset and scale. This
allowed a lot of simplification since it no longer needs to manually do
the transformation calculation and instead can rely on functions
provided by the Transform class.
Test: Input works
Test: inputflinger_tests
Test: libinput_tests
