[meson] Update cairo subproject

Update to the current master branch so that is has
cairo_user_font_face_set_render_color_glyph_func().

I had to disable optimized builds on win[32|64] crossbuild setups
because they are now broken in the CI (something about cairo defining
_FORTIFY_SOURCE for optimized builds that MingW does not like).
