wayland_common: rewrite from scratch

The wayland code was written more than 4 years ago when wayland wasn't
even at version 1.0. This commit rewrites everything in a more modern way,
switches to using the new xdg v6 shell interface which solves a lot of bugs
and makes mpv tiling-friedly, adds support for drag and drop, adds support
for touchscreens, adds support for KDE's server decorations protocol,
and finally adds support for the new idle-inhibitor protocol.

It does not yet use the frame callback as a main rendering loop driver,
this will happen with a later commit.
