    girwriter: Add fullname GIR attribute, and set fullname of GObject.Type
    
    In gir files generated by Vala, members of type GType is referenced
    with name "GObject.Type", but GObject-introspection expect it to be
    "GType".
    
    While there was no way to override the fully qualified GIR name of a
    member, this patch adds [GIR (fullname = "GType")] to fix the mismatch
    for GObject.Type.
