Switch to an always-on realization mode for Coq.

There are hardly any change to the code. It now just looks whether
dependencies are marked as realized. The old no-realization mode is
equivalent to marking no theory as realized, while the old realization
mode amounts to marking all of the theories as realized. Now, the finer
granularity make any intermediate state reachable. This is just a proof
of concept, so the actual set of realized theories is hard-coded.
