Add touchscreen rotation precision tests

Add tests to verify that a touchscreen that is associated with a display
produces exactly the correct coordinates in four of the display's
orientations.

In these tests, the touchscreen is configured in the default
orientation. We then verify that when the display is rotated,
we get the expected values.
