* This is primarily for the benefit of GL/VK where we need to feature-detect for
some extensions or functionality that requires selecting a device, e.g. D3D12
can be more easily detected with a quick check.
* We'll run this once and cache the results when running tests from python so we
can do a better job of filtering out tests that the current machine doesn't
support.
* Built entirely independently of the main renderdoc build (for now).
* Contains python scripts & framework for running tests on a renderdoc build,
which will be run nightly.
