Before we would try all the configs and filter those which fail to
init. Now we gather the System Info and if successful check a list of
supported configs. If System Info init fails we fall back to the prior
method.

This speeds up end2end tests init. It also allows for more reliable
profile captures with VTune. It also will cause a test failure if a
config unexpectedly fails. Previously we would silently pass without
running the config's test. Includes a few changes:

 * D3D reference tests are disabled. They don't appear to be working.
 * Mac ES 3.1 is disabled due to lack of support.
 * WGL on AMD Windows is disabled due to lack of ES compatibility.
 * ES 3.2 contexts are explicitly disabled.
 * Vulkan is limited to ES 2.0.
 * The Windows GLES back-end is limited to NVIDIA with ES 2.0 & 3.0.
 * A unit test that verifies the whitelist matches availability.
