Michael Olbrich 40364c2c09 libs: wayland: implement video overlay API
The Wayland sub-surfaces API is used to embed the video into an application
window.

See Appendix A. Wayland Protocol Specification as the following.

"""
The aim of sub-surfaces is to offload some of the compositing work
within a window from clients to the compositor. A prime example is
a video player with decorations and video in separate wl_surface
objects.

This should allow the compositor to pass YUV video buffer processing to
dedicated overlay hardware when possible.
"""

Added new method gst_vaapi_window_wayland_new_with_surface()
