    build: Add a GIR dependency to PangoCairo
    
    This is not strictly needed from an introspection perspective, but:
    
     - GTK strictly depends on PangoCairo internally
     - we want to integrate the GDK docs with PangoCairo's
    
    So even though we don't have an explicit dependency on PangoCairo types
    in our ABI, we do assume that people will be able to use the PangoCairo
    API with GTK.
