Use DisplayVkSimple on ChromeOS Currently, we always use DisplayVkHeadless on ChromeOS which can fail if the drivers do not support VK_EXT_headless_surface (e.g. Intel). This CL changes the default to use DisplayVkSimple which requires VK_KHR_display which is better supported. At the end of the day, CrOS never really uses Vulkan WSI, so the actual WSI extension used doesn't matter.
