[PATCH 1/1] tests: Use a pixel shader that consumes SV_Position in test_query_pipeline_statistics().

[Zebediah Figura]

From: Zebediah Figura

Some drivers (AMD Radeon RX 6700 XT, with radeonsi from Mesa 22.2.0-rc3) emit
less than one invocation per pixel, presumably because they detect that the
shader control flow is uniform for all pixels. Having the control flow depend on
SV_Position avoids this test failure.

Cf. 34bd0dd0704c613abef8a9aa3ba2a2507ed02843 in wine.
