Subject: [PATCH] Use `AtomLayoutResponse` in `TextEditOutput` (#8003)

This is necessary to add e.g. buttons as prefix/suffix within the
textedit (so you can read the rect and place the button).

I'm not sure if deref on the AtomLayoutResponse is the right call but it
should make the migration easier and is generally convenient (but might
lead to some confusion).
