testgen: added EIP 7702 transaction receipt test and SignAuth

[PelleKrab]

Changes:

• Added eth_getTransactionByHash, eth_getTransactionReceipt, and eth_getTransactionRawTransaction test.
• Added SignAuth() to simplify SetCode authorization signing.

I've opened #39 for Prague tests. Would be nice to rebase this once that's in. Some 7702 things are already covered by #39, but transaction sending isn't.

[PelleKrab]

Everything is working except send-authorization-list-tx is getting a "failed to fill eth_sendRawTransaction/send-authorization-list-tx: transaction type not supported: received type 4" error. Not sure if this is an rpctestgen config issue, but I am looking into it, and ./mkchain.sh seems to be working.

The issue is go-ethereum master doesn't include 7702 into the legacy subpool. I implemented this on my local repo and the test filled. Should I make a PR on go-ethereum or is this intentional? @fjl

[fjl]

It's intentional. We are still working on proper 7702 support in txpool. It's not as simple as just enabling it.

[PelleKrab]

So 7702 transaction sending in rpctestgen is blocked until proper support is figured out, correct?

[fjl]

Yeah, for now.

I have removed the tx send test for now. We can add this later when Geth supports it.
