  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.
  - XCB display availability check.
