  Original change's description:
  > Re-land: "Vulkan: Support Wayland"
  >
  > Implement DisplayVkWayland and WindowSurfaceVkWayland. Get window size
  > from native window and check egl config is just empty. An EGL wayland
  > test is added for testing rendering and buffers swapping.
  >
  > Re-land fixes link failure in systems with no libwayland installed.
