    guri: add some IPv6 scope-id tests
    
    Add a few ipv6 scope parsing corner test cases.
    
    - checking incorrect scoped IPv6 ending with only %25 isn't decoded.
    - checking valid scoped IPv6 is passing g_uri_is_valid()
    
    As discussed in
    https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1567#note_860499,
    for historical reasons, GUri accepts the % preceding the zone-id in the
    unescaped form as well.
