vo_dmabuf_wayland: scale smarter in hidpi situations

Browse Source 
Previously, all scaling was forced to 1 with this vo and all coordinates
were calculated as if the scale was 1. This works since viewport relies
on the compositor completely for scaling so it doesn't really matter if
we don't draw directly to the correct size since the compositor will
just scale the rest for us. This does have some downsides however since
the OSD text might not be drawn at the actual resolution of the final
size of the video.

We can instead handle this by getting rid of the dmabuf_wayland specific
scaling logic and using the same values as everything else. In the
resize in vo_dmabuf_wayland, we just need to adjust the viewport
destination calls so they go to the wayland local coordinates and not
the physical ones. This should ensure that vo_dmabuf_wayland directly
goes to the desired size and the compositor doesn't need to operate on
it after the fact.
