[Feature] Add specializations for Signed types for OpTransaction<TxEnv>

[mattsse]

Describe the feature you would like

rn we only support going from the envelope to the OpTransaction<TxEnv>

evm/crates/evm/src/op/tx.rs

Lines 45 to 50 in f3e5d1d

	impl FromTxWithEncoded<OpTxEnvelope> for TxEnv {
	fn from_encoded_tx(tx: &OpTxEnvelope, caller: Address, _encoded: Bytes) -> Self {
	Self::from_recovered_tx(tx, caller)
	}
	}

evm/crates/evm/src/op/tx.rs

Lines 51 to 67 in f3e5d1d

	impl FromTxWithEncoded<OpTxEnvelope> for OpTransaction<TxEnv> {
	fn from_encoded_tx(tx: &OpTxEnvelope, caller: Address, encoded: Bytes) -> Self {
	let base = TxEnv::from_recovered_tx(tx, caller);
	let deposit = if let OpTxEnvelope::Deposit(tx) = tx {
	DepositTransactionParts {
	source_hash: tx.source_hash,
	mint: Some(tx.mint),
	is_system_transaction: tx.is_system_transaction,
	}
	} else {
	Default::default()
	};
	Self { base, enveloped_tx: Some(encoded), deposit }
	}
	}

while for just TxEnv we also support:

evm/crates/evm/src/tx.rs

Lines 255 to 261 in f3e5d1d

	impl FromTxWithEncoded<TxEip4844> for TxEnv {
	fn from_encoded_tx(tx: &TxEip4844, sender: Address, _encoded: Bytes) -> Self {
	Self::from_recovered_tx(tx, sender)
	}
	}
	impl FromRecoveredTx<TxEip7702> for TxEnv {

ideally we have the same

this means effectively inlining this per tx implementation:

evm/crates/evm/src/op/tx.rs

Lines 51 to 65 in f3e5d1d

	impl FromTxWithEncoded<OpTxEnvelope> for OpTransaction<TxEnv> {
	fn from_encoded_tx(tx: &OpTxEnvelope, caller: Address, encoded: Bytes) -> Self {
	let base = TxEnv::from_recovered_tx(tx, caller);
	let deposit = if let OpTxEnvelope::Deposit(tx) = tx {
	DepositTransactionParts {
	source_hash: tx.source_hash,
	mint: Some(tx.mint),
	is_system_transaction: tx.is_system_transaction,
	}
	} else {
	Default::default()
	};
	Self { base, enveloped_tx: Some(encoded), deposit }

and then updating this impl for envelope like:

evm/crates/evm/src/tx.rs

Line 431 in f3e5d1d

impl<Eip4844: AsRef<TxEip4844>> FromTxWithEncoded<EthereumTxEnvelope<Eip4844>> for TxEnv {
