video/out: introduce VOCTRL_UPDATE_WINDOW_TITLE

Instead of implicitly changing the window title on config(), do it as
part of the new VOCTRL.

At first I wanted to make all VOs use the VOCTRL argument directly, but
on a second thought it appears vo_get_window_title() is much more useful
for some (namely, if the window is created lazily on first config()).

Not all VOs are changed. Wayland and OSX have to follow.
