skins2(Windows): fix sporadic vlc hangings at termination

As skins2(Windows) runs in the main thread, special care must be given to playlist/input/vout termination. Up to now, vout threads kept on running with the GUI event loop no longer operational, leading to vlc hangings.
(cherry picked from commit b1680840287cea049b8ad1e1ff8be0de96f101e4)
