[pango/wip/meson: 3/10] Add prototype for _pango_color_parse_with_alpha()

[Emmanuele Bassi <ebassi src gnome org>]

commit 779619ad6712fe9e5c4dabfef61e092e7a8f09f0

    Add prototype for _pango_color_parse_with_alpha()
    
    It's used in pango-markup.c and pango-color.c, so it should have an
    internally-available prototype, instead of an `extern` declaration at
    the point of use.
    
    This also avoids a compiler warning for a missing prototype.
