This PR update the signing message of funding lock and commitment lock(with pending htlc).
In the original code, the signing message was tx_hash. This approach faces challenges during script upgrades because the cell_dep field in the transaction became invalid, which causes the entire transaction invalid.
To resolve this, we empty
RawTransaction#cell_dep
field, then useblake2b_256(&raw_tx.as_slice())
to get the signing message.
