add returndata to transaction receipts where available

[charles-cooper]

Describe the feature

per ethereum/execution-apis#542

Additional context

the proposed change to the api spec makes it optional to include returndata. the first implementation step could be to just add the returnData field with a value of nil, and then the second implementation step is to fill it in when it makes sense

[mattsse]

fill it in when it makes sense

when would this be the case?

[charles-cooper]

from the perspective of the user, ideally, all the time - which would mean re-running the transaction or caching the returndata in a separate database. "when it makes sense" just means subject to performance constraints.
