[pango/coverage-redo: 1/4] Add pango_font_covers

[Matthias Clasen <matthiasc src gnome org>]

commit 481e1be4647f691139d953b91ad81b88e0dc6f3b

    Add pango_font_covers
    
    Add a pango_font_covers function, which is like
    pango_shape_engine_covers, without the engine.
    
    This api is simpler than PangoCoverage in that
    it does not take a language as input, and only
    returns a boolean.
    
    This matches the harfbuzz api.
