Previously, none of our `runtime` tests relied on the input coordinate in any way, so all of the logic was hoisted above the main loop in every test. This CL adds an artificial reliance on the input coordinate so that we have at least some SkVM tests with real code in the main loop. This lets us see debug trace instructions interleaved with real code. The input coordinate is clamped against a known uniform value (`colorGreen` always contains 0101) so that the final test output remains consistent in practice. Additionally, I noticed that this test was only enabled in ES3, but it doesn't seem to have anything ES3-specific in it, so it's now enabled across the board.
