  Message : Vulkan:Adding Cmd Buffer Reset tests Resetting cmd buffers in various ways to understand VK driver perf on various devices. Also includes some changes to get the chromium APK wrapper for angle_white_box_perftests compiling. Bug: angleproject:3137 Change-Id: I56bd163cdd6605ce09effe509a9c7ac5e0008e7a Reviewed-on: https://chromium-review.googlesource.com/c/1456482 Commit-Queue: Tobin Ehlis <tobine@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
