Integrate ChirDv into the composite pipeline.

Now that SSLSO includes the ChirDv (goat life stages) component, we
should make sure the bridging/composite pipeline is ready to deal with
that component: we must generate bridging axioms between the Uberon life
stages terms and their ChirDv counterparts, and unfold them into class
expressions when building Composite Metazoan.

Otherwise, the ChirDv terms would still end up in the
collected/composite products (since they are bundled with SSLSO), but
would not be connected to Uberon’s hierarchy.
