Port to GTK 4
We probably want to port to GTK4 as soon as we can. Let's use this issue to keep track of the progress.
This is currently blocked on several things:
-
libhandy → use libadwaita instead -
cheese-gtk → not a hard blocker, but would still be useful -
gnome-desktop → since we don't have thumbnail preview anymore, we can drop this (I think) -
libedataserverui → not sure here...
