Propagate focusObjectChanged signal (second attempt)

When the focus object is updated from inside the Qt Quick scene,
the signal needs to be propagated from the offscreen window to
the widget's window, otherwise the input methods will not react
to it.

Also, we need to propagate the FocusAboutToChange event,
otherwise the contents of the editor will not be committed
when the focus object changes, and the input method can
get into an invalid state.
