[pango] meson: Rework gir/typelib generation and dependencies

[Nirbheek Chauhan <nirbheekc src gnome org>]

    meson: Rework gir/typelib generation and dependencies
    
    Don't use --include-uninstalled, it's not needed with Meson because we
    take care of inter-gir target dependencies.
    
    Add girs and typelibs to the relevant libpango*_dep declared
    dependencies so that they can be used via subprojects.
