Remove cross-era nested definitions of predicate failures

There are a few places in pre-Conway eras, where a predicate failure type wraps the the predicate failure from the same rule but from the prior era, eg

https://github.com/IntersectMBO/cardano-ledger/blob/eb123e6035b9cf2f195be9df64e89115c6155a39/eras/babbage/impl/src/Cardano/Ledger/Babbage/Rules/Utxo.hs#L111

This needs to be fixed for all pre-Conway eras.

* [ ] - First part of the ticket is two identify all those cases

* [ ] - Second part is two inline all those predicate failures, like it is done in Conway.
