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

Start with execution/evm/execution.go at lines 134-142 and trace the initial transaction-list iteration and the later checks described in the issue. Determine whether the checks can be combined without changing behavior, then verify that transaction processing still produces the same results and that the extra iteration is removed.
