  Message : Re-land "Add a small unit test that dumps system info." Re-land fixes the GL APIs accidentally leaking into the test. We can use this in the trace gold tests to identify system properties. The test uses Vulkan info collection when available and dumps out the known GPU info as JSON. Bug: angleproject:4090 Bug: b/168049670 Change-Id: I1481fee14ed8c573f10164d74ec27701e1ad80ff Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2433090 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
