refactor: Simplify `extra_txn` to be a vec of CTransactionRef instead of a vec of pair<Wtxid, CTransactionRef>

All `CTransactionRef` have `.GetWitnessHash()` that returns a cached `const Wtxid` (since fac1223a568fa1ad6dd602350598eed278d115e8),
so we don't need to pass transaction refs around with their IDs as they're easy to get from a ref.
