Optional Datum for PlutusV3: CIP-0069

[lehins]

It has been decided that we need to implement CIP-0069 for Conway era and PlutusV3

The work has already been mostly done on the Plutus side: IntersectMBO/plutus#5934

What needs to happen on the ledger side:

• - Customize datum checking in the UTXOW rule to not require Datums for spending inputs
• - Customize plutus interface to require only one argument for PlutusV3 instead of a list of datums
• - Change the PlutusContext representation for PlutusV3 and adjust TxInfo translation accordingly

Fixed in #4374
