Introduce OpPooledTx trait

[klkvr]

Describe the feature

We need to provide op payload builder with access to conditionals and encoded bytes of transaction

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

Lines 29 to 30 in 8c0f25d

	/// The estimated size of this transaction, lazily computed.
	estimated_tx_compressed_size: OnceLock<u64>,

We can solve this with an additional trait for op pooled transaction which would need to have MaybeConditionalTransaction and PoolTransaction as supertraits.

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

Line 7 in 8c0f25d

pub trait MaybeConditionalTransaction {

Once the trait is introduced we can change bounds for OpPayloadBuilder to enforce it

reth/crates/optimism/payload/src/builder.rs

Line 162 in 8c0f25d

Pool: TransactionPool<Transaction: PoolTransaction<Consensus = N::SignedTx>>,

TODO

• introduce trait OpPooledTx: MaybeConditionalTransaction
