[pango/pango2: 52/63] Add default fontmap API

[Matthias Clasen <matthiasc src gnome org>]

commit a17046d856e2d2bda90297369d48f54c32c61c31
Author: Matthias Clasen <mclasen redhat com>
Date:   Wed Jun 8 20:41:14 2022 -0400

    Add default fontmap API
    
    Now that all our fontmaps handle the same kinds
    of fonts, we can make the default fontmap a
    frontend api, and not longer cairo-specific.
