Add touchscreen orientation precision tests

Add tests to verify that a touchscreen that is configured in any of the
four orientations generates the expected coordinates in the unrotated
display's coordinates. A touchscreen's orientation determines how the
input device is oriented relative to the natural orientation of the
display.

In this test fixture, the input device has twice the resolution of the
display along the shorter dimension and four times the resolution of the
display in the longer dimension.
