feat: support directly forward transactions to sequencer

[yiweichi]

Reth counterpart of l2geth scroll-tech/go-ethereum#1208.
Related rollup-node PR: scroll-tech/rollup-node#189

Implemented a SequencerClient, which will help to forward transaction to sequencer's RPC directly(support both http and ws). Whether a transaction forwarding succeed or not, the transaction will be added to local transaction pool.

Instead of modifying the constructor for EthTransactionValidatorBuilder we should use the pre-existing with_local_transactions_config to set the LocalTransactionConfig. This minimises the diff with upstream which is a priority for us.

Looks good. Left some comments inline around logging. We should prefix the target with scroll:: such that when we filter logs using RUST_LOG=scroll=trace we can correctly filter the appropriate target. Otherwise, these logs may get lost.
