Improve OP txpool batch validation

[mattsse]

Describe the feature

the opvalidator currently does:

reth/crates/optimism/node/src/txpool.rs

Line 411 in 6dabd52

transactions.into_iter().map(|(origin, tx)| self.validate_one(origin, tx)).collect()

and delegates to the regular eth validator:

reth/crates/optimism/node/src/txpool.rs

Lines 334 to 346 in 6dabd52

	pub fn validate_one(
	&self,
	origin: TransactionOrigin,
	transaction: Tx,
	) -> TransactionValidationOutcome<Tx> {
	if transaction.is_eip4844() {
	return TransactionValidationOutcome::Invalid(
	transaction,
	InvalidTransactionError::TxTypeNotSupported.into(),
	)
	}
	let outcome = self.inner.validate_one(origin, transaction);

this is suboptimal for batches because the eth validator is optimized for batches.

we can improve this by delegating to

reth/crates/transaction-pool/src/validate/eth.rs

Lines 498 to 499 in 6dabd52

	/// Validates all given transactions.
	fn validate_batch(

first and then perform the additional OP checks.

TODO

• split delegated validation from validate_one

  reth/crates/optimism/node/src/txpool.rs

  Line 346 in 6dabd52

  let outcome = self.inner.validate_one(origin, transaction);

• improve Op validate_batch
