Generate fixtures for these test cases for Prague with:

fill -v tests/prague/eip7702_set_code_tx/test_set_code_txs.py::test_set_code_to_tstore_available_at_correct_address --fork Prague

Test TLOADing from slot 2 and then SSTORE this in slot 1, then TSTORE 3 in slot 2. This is done both from the EOA which is delegated to account A, and then A is called. The storage should stay empty on both the EOA and the delegated account.
