[pango/pango2: 292/301] Drop more PangoItem api




commit 00f67ab0e8e4f7834ec0dce71b08514b608071d8
Author: Matthias Clasen <mclasen redhat com>
Date:   Mon Jun 20 10:12:17 2022 -0700

    Drop more PangoItem api
    
    There is no way to do anything useful outside
    of Pango with these functions, so keep them
    private.
