fix(txJSON): L1 message type MarshalJSON

[colinlyguo]

1. L1 message type tx marshaling is accidentally removed in: feat(transactions): support blob tx only in encoding/decoding #626
2. change sender field to optional, thus in other transaction types, the sender field is omitted.

The bug would not affect the newly redeployed bridge-history-backend because l2geth uses RPCTransaction to marshal transactions.

1. RPCMarshalHeader and RPCMarshalBlock are both missing several fields compared with upstream. This PR would not add them for the moment.
2. data -> input in txJSON does not break current prover's witness:
   i. RPCs (GetBlock, GetTransaction) use RPCTransaction to marshal transactions from rlp-encoding to JSON.
   ii. GetTrace uses TransactionData to marshal transactions.
   iii. Transaction Receipt uses its own marshaling.
