x11: support XEmbed
Seems to work with GtkSocket and passing the gtk_socket_get_id() value via "wid" option to mpv. One caveat is that using <tab> to move input focus from mpv to GTK does not work. It seems we would have to interpret <tab> ourselves in this case. I'm not sure if we really should do this - it would probably require emulating some other typical conventions too. I'm not sure if an embedder could do something about this on the toolkit level, but in theory it would be possible, so leave it as is for now.
