[pango/pango2: 45/63] Drop some font family apis

[Matthias Clasen <matthiasc src gnome org>]

commit 3fc3e677e15d547ecf603aec1cd3ff25b31293f9
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.
