Support creation_code and runtime_code contract type information

[pcaversaccio]

Summary

Related to comment: #4204 (review). Having the contract type information:

• creation_code
• runtime_code
  would be very useful in conjunction with the new raw_create() built-in (see issue VIP: add new built-in function raw_create #3710 and PR feat[lang]: add raw_create() builtin #4204). Like that you could for example do raw_create(erc20.creation_code, ...). The runtime_code can be used to retrieve, hash, and compare it at creation time to the real codehash at the deployed address for example.

note that this will increase compilation time by a lot, since the compiler has to do full code generation for another module

@pcaversaccio do we actually need .runtime_code? i don't think it will correspond to real codehash unless you have the immutables section already.

I think it's "nice-to-have" rather a "must-have" for now.
