Stabilizing wl_scaler protocol extension

I use it in my wayland-next branch (for unstable wayland stuff) of the mpv
In this commit:
I only just now realized that I should just use set_destination for my use
So setting the destination separately is definitely a use case and I think
the set request is redundant.
So far I really like the scaler extensions. But the scaling quality has
lots of room for improvement.
I thought about improving the scaling quality, but didn't had the
opportunity to look into it.
That's all from me.
