Switch faders to layer-shell-effects
We can switch the faders
-

output fader -
fader used for proximity dimming
(see the CSS stylesheet)
to use compositor side fading.
With layer-shell effects protocol merged we can switch the above faders to use that protocol rather than doing it on the GTK side which should make things look smoother. We'd basically follow what !1253 (merged) does.
Filing this as an issue rather than doing it right away as it's best to do this past 0.28.0 so we don't need to worry in more places whether phoc supports this. It's also a nice task in case someone wants to get into phosh development.
