Description

Meant as a replacement for pull request #4314 Does several things

1. Generalizes many of the instances in Test.Cardano.Ledger.Constrained.Conway.Instances to all Eras (not just Conway)
2. Introduces two new types SimplePParams and SimplePPUpdate that are the used as the SimpleRep type across all Eras, makes it much easier to write specifications for PParams and PParramUpdates in all eras
3. Writes specifications for all the Cardano types used in NewEpochState, EpochState, LedgerState, UTxOState etc.
