tests: add output damage test

This test ensures that client submitted damage goes to the screen
correctly, regardless of output scale or transform.

The added quirk is explained in the test that uses it.

* The following quirk forces GL-renderer to update the whole texture
* even for partial damage. Otherwise, GL-renderer would only copy the
* damaged area from the wl_shm buffer into a GL texture.
*
* Those output_damage tests where the surface is scaled up by the
* compositor will use bilinear texture sampling due to the policy
* in the renderers.
*
* Pixman renderer never makes copies of wl_shm buffers, so bilinear
* sampling there will always produce the expected result. However,
* with GL-renderer if the texture is not updated beyond the strict
* damage region, bilinear sampling will result in a blend of the old
* and new colors at the edges of the damage rectangles. This blend
* would be detrimental to testing the damage regions and would cause
* test failures due to reference image mismatch. What we actually
* want to see is the crisp outline of the damage rectangles.
