Create opcode test cases generator

[marioevz]

For a future PR:

I think we can generalize these into a test generator:

Given (1) an Opcode, (2) a list of verification stack inputs/ouputs combinations, test the opcode in many different contexts and verify it works correctly, including Call-contexts, contract creation contexts, 7702 delegation context, etc.

Something like:

def generate_context_tests_for_opcode(
    opcode: Op,
    inputs_outputs: List[Tuple[List[int], int]],
):

And then on a test file you can do:

@generate_context_tests_for_opcode(
    opcode=Op.CLZ,
    inputs_outputs=[ ( [0x01], 0x01 ), ( [0xff], 256 - 8 ), ...
)
def test_clz_in_all_contexts(
...
