Add Wayland output module.
Wayland API has been stable for some time now. I guess it would be nice for VLC to have Wayland video output module. I noticed that there has been some work on EGL output so it provides a good start since Wayland uses EGL and such.

If output module is present, VLC can be ran on Wayland when it moves to Qt5 which already works with Wayland.
