Notable differences from the existing fake CI bots:
1. Instead of splitting the bots by dEQP/non-dEQP they are split now by
   Chromium/ANGLE-specific, which means:
2. Suites which don't depend on Chromium, like angle_end2end_tests and
   angle_perftests now run together with dEQP suite.
3. Some tests suites were removed from ANGLE bots - gpu_unittests,
   as well as all GLES2 conformance tests.
