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.
