Generate fixtures for these test cases for Amsterdam with:

fill -v tests/cancun/eip5656_mcopy/test_mcopy_contexts.py::test_no_memory_corruption_on_upper_create_stack_levels --fork Amsterdam

Perform a subcall with any of the following opcodes, which uses MCOPY during its execution, and verify that the caller's memory is unaffected: - CREATE - CREATE2.
