[gtk/fix-4565: 1/2] gtkfontchooserwidget.c: Fix build with pre-1.44.x Pango

[Chun-wei Fan <fanchunwei src gnome org>]

commit b0e3d0383199d322ad0175609cd215ace969315d

    gtkfontchooserwidget.c: Fix build with pre-1.44.x Pango
    
    Pango headers after 1.44.0 include hb.h automatically, but not before, so
    re-structure the #if/#elif/#else checks for the availability of HarfBuzz 2.2.0
    or later.
    
    Pointed out in issue #4565.
