  Use offscreen DisplayVk on ChromeOS
  
  Currently, we always use DisplayVkHeadless on ChromeOS which can
  fail if the drivers do not support VK_EXT_headless_surface (like on
  Intel). At the end of the day, CrOS never really uses Vulkan WSI, so
  it shouldn't need a WSI extension anyways.
  
  This CL introduces a simple DisplayVkOffscreen that requires no WSI.
  We then configure CrOS to use this new DisplayVk.
