Carlos Garnacho 237ba24dbe ibusCandidatePopup: Set OSK candidates list visibility correctly
Right now, we don't pay much attention to visibility hints from IBus
about the candidates list for the OSK suggestions bar. Since some
IMs rely on this visibility being honored, do that.

To fix this, the visibility hints for the lookup table are now
propagated to the keyboard, so the Suggestions actor hides its
internal candidate buttons. Since the Suggestions actor gets its
minimum height from CSS, this does not result in OSK size jumps.

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/5601
