Stop running WebGL 2.0 conformance on AMD on win_angle_rel_ng.

There aren't enough Windows AMD machines to run this test suite on AMD
GPUs against all ANGLE CLs. The suite runs on NVIDIA and Intel GPUs,
and the AMD-specific version doesn't catch many errors at this point,
so accept the potential for waterfall-only failures.
