vo_dmabuf_wayland: support osd rendering when there's no video 

The osd support was originally written with the requirement that we have
actual frames getting delivered to the VO. This isn't always the case
though. If you force a window on a blank audio file for example, then
there will be no frame thus draw_frame did nothing. Since the previous
commit allows us to reliably detect this, we can rearrange the code
around a little bit to make this possible. A key change is to make the
osd_subsurface have wl->surface as the parent. This is seemingly
required otherwise the osd_surface buffers are never visible above the
empty video_surface when we have a black window. Also nuke the desync
call since it's completely pointless. Fixes #12429.
