[nautilus/wip/antoniof/gtk4-pre-switch-regressions: 5/9] icon-info: Remove unused or single-use API

[António Fernandes <antoniof src gnome org>]

commit 88b3e193476660a8dcbf760acf0cbd86d900fe0a

    icon-info: Remove unused or single-use API
    
    The single-use functions can be dropped because:
    
      - in properties-window, we can just make and pass a GIcon.
      - in files-view, we can just use the NautilusFile method.
    
    There is a potential change in behavior in that files-view
    now may get the default icon. That's not a problem at all.
