magnifier: Use the new get_client_content_rect API

As we have removed is_client_decorated from Mutter in the last release.
Instead of re-adding it and re-exposing SSD/CSD differences and making
gnome-shell deal with that, we created a new API that does exactly what
is_client_decorated was used for, so switch to using that.

Closes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/7984
