TouchInputMapper: Use ui::Transform to calculate orientation angles

Rather than manually re-orienting the calculated angles for orientation
and tilt, we use the transform to compute the oriented values for these
non-planar axes. This approach is both less error-prone and less verbose.

In this CL, we also transform the coverage rect from raw to display
space using the computed transform.
