shell/app: Add new get_icon() method

Now that we can always associate a GIcon with the app, add a method
to access it. While create_icon_texture() is still likely to be more
convenient in most cases, exposing the icon can still be useful, for
example to add it to a different kind of actor or to compare it with
other GIcons.
