Gets whether gtk_widget_set_hexpand() has been used
to explicitly set the expand flag on this widget.
If [property@Gtk.Widget:hexpand] property is set, then it
overrides any computed expand value based on child widgets.
If hexpand is not set, then the expand value depends on
whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here
for completeness and consistency.
