Generate fixtures for these test cases for Osaka with:

fill -v tests/osaka/eip7692_eof_v1/eip4750_functions/test_code_validation.py::test_callf_stack_height_limit_exceeded --fork Osaka

Test for invalid EOF code containing CALLF instruction exceeding the stack height limit. The code reaches the maximum runtime stack height (1024) which is above the EOF limit for the stack height in the type section (1023).
