optimization: Explore reducing number of transaction list iterations

https://github.com/evstack/ev-node/blob/04637e6ee86b8a9f22440322b77e7775ce2d8dab/execution/evm/execution.go#L134-L142

was referring this iteration, we go over the list of txs in `ev-node`. If we just do all these checks during the initial iteration, it helps reduce another iteration.

Albeit, I think this would only be relevant if we're in the 10^6 range of txs per block which I don't think we're at yet.

Assuming a program can do a 10^9 ops/second, which is 10^6 ops/millisecond. If we're targeting 50 ms block times, that's 5*10^7 ops/millisecond. So approximately, reducing the multiple iterations only start translating to performance gain at 10^6 tx range

execution/evm/execution.go の134-142行目から始め、トランザクションリストの初回の反復処理と、issueで説明されている後続のチェックを追跡します。動作を変更せずにチェックを統合できるか判断し、その後、トランザクション処理が引き続き同じ結果を生成し、追加の反復処理が削除されていることを確認します。
