    altTab: Remove get_preferred_width override of AppIcon
    
    This vfunc override has been introduced to ensure app icons are always
    squared, but since the container of the AppIcon gets a square allocation
    anyway if the 'square' property of the SwitcherButton is set, there's
    no need to return a special width here.
    
    Without the override we can also stop setting the size of the iconBin
    manually. And since shell_app_create_icon_texture() uses logical pixels
    but clutter_actor_set_size() uses screen pixels, that means we now no
    longer set the size of the icon back to the unscaled value after it was
    already correct.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/1325
    
    
    (cherry picked from commit 074129682bc134f4ca0005a8d9edef210e30da69)
