We're interested in a Vulkan-only stack in Chrome OS, where Android's GLES would be provided by ANGLE-over-Venus-over-ANV. Let's get some testing covering ANGLE-on-ANV first. This is structured as a single partial job pre-merge to catch most regressions, and a longer manual job to do full coverage for when you need to update the xfails list.
