[pango/pango2: 172/301] Drop some font family apis

[Matthias Clasen <matthiasc src gnome org>]

commit 7c103cc00afa10d29748063c3ecee3d5f7596396
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Jun 7 21:56:29 2022 -0400

    Drop some font family apis
    
    Drop pango_font_family_is_monospace/variable/generic,
    since these are better as face apis.
