Generate fixtures for these test cases for Amsterdam with:

fill -v tests/prague/eip7702_set_code_tx/test_set_code_txs.py::test_creating_delegation_designation_contract --fork Amsterdam

Tx -> create -> pointer bytecode.

Attempt to deploy contract with magic bytes result in no contract being created.
