chore(execute): evaluate feasibility of an execute simulator for RPC testing

The `execute` simulator runs consensus tests, but we could extend its capability by adding a new test type that has the potential to additionally detect RPC bugs (e.g. delays or failure propagating state to endpoints) by using a test's `post` state to verify that changes propagate correctly and timely through client/RPC.

An example is this bug:
- https://github.com/ethereum/go-ethereum/issues/31798

which was found by `test_async_sign_authorization_and_send_raw_set_code_transaction()` an [ethereum/web3.py](https://github.com/ethereum/web3.py) / [ethereum/py-geth](https://github.com/ethereum/py-geth/) unit test.

This wouldn't be a consensus test specific simulator, just a different use case of the consensus tests.
