ibusCandidatePopup: Fix scaling set-cursor-location-relative signal handling

Need to convert the raw coordinates to the scaled ones in gnome-shell.
IBus GtkIMModule can calculate the relative coordinates and gnome-shell
needs to provide the actual scale.

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/8424
Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/3729>
(cherry picked from commit 2b2456e87d02b36fa85cdf434011f44143688215)
