1.0.x/conformance/rendering/texture-switch-performance.html fails on AMD dgpu Metal

 FAIL Texture switching significantly hurt performance - achieved 52 frames in 2.005 seconds (0.47 times baseline performance)

Note - don't worry too much about this specific conformance test - I think its thresholds may be too strict for it to pass reliably on most platforms. On the other hand, if you see an optimization that would improve it on AMD GPUs with ANGLE's Metal backend - that would address the primary concern of the test, which was designed to expose issues with AMD GPUs on Apple's OpenGL driver.
