refactor: let pevm::execute accept spec_id as a parameter

[kien-rise]

One step towards https://github.com/risechain/pevm/issues/60

We are gonna have:

let spec_id = get_optimism_block_spec(&block.header)?;
let result = pevm::execute(
        &db,
        chain,
        spec_id,
        block.clone(),
        concurrency_level,
        true,
);
