tapdb+universe: consolidate code, link commitment to previous one

We clean up and consolidate a bunch of code:
 - Parsing the supply commitment and data was duplicated, is now
   a single function.
 - The commitmentChainInfo can be merged directly into the
   commitment.CommitmentBlock, gets rid of a parameter.

We also add a new spent_commitment field to the supply_commitments table
that tracks the previous commitment transaction that was spent, to
create the full chain.
To be able to traverse that chain, we also need to be able to query the
commitments either by a commitment's outpoint or by the outpoint a
commitment is spending, which allows backward lookup in a loop.
