fix(tests): EIP-7702: send tx of eoa after setcode tx is mined

[sonhv0212]

🗒️ Description

Currently, the test test_eoa_tx_after_set_code is including both setcode tx that sets code for an EOA and tx using EOA as sender in same block. However, it is invalid due to changes introduced in this PR ethereum/go-ethereum#31430. When I try to run this test in execute mode, the second tx is rejected with the error gapped-nonce tx from delegated accounts

Here is my solution to fix it:

• I split txs into two blocks; the first includes setcode tx that set code for an EOA, and the second is the tx from that EOA
• We need to ensure txs of two different blocks must be included in different block as their order in node, so I refactored TransactionPost a little bit to send batches of txs by block.

cc @marioevz , seems that you're the author of this test case. Can you help me verify this?
Thank you!!! 😄

LGTM, thanks for these changes, I think it's a good idea to make this distinction.

I added a parametrization to fill the same test as it existed before this PR, whilst skipping it for execute, and the new variant you introduced.
