    files-view: Remove unused API
    
    nautilus_files_view_handle_scroll_event() is being called only once by nautilus_files_view_scroll_event() 
in the whole nautilus code base.
    
    So remove it's declaration from it's header file, and move it's code to 
nautilus_files_view_scroll_event() directly.
    
    Note - nautilus_files_view_handle_scroll_event() used to be used by compact view, which was removed in 
commit  https://gitlab.gnome.org/GNOME/nautilus/commit/241e462024070d9f79f4816256fc00ff5119e25f
