feat(fw): Add with_all_contract_creating_tx_types marker

[marioevz]

🗒️ Description

• Makes the transaction class more permissible to always allow the creation of a valid transaction with the minimum number of set fields (in order to more easily parameterize the same test with multiple transaction types without having to worry about the specifics of each type).
• Fix for evmone when passing a contract-creating tx: Use tx: "" instead of tx: null.
• Add a contract_creating_tx_types to all forks to return all the supported transactions that can create contracts for the given fork.
• Add a new covariant marker called with_all_contract_creating_tx_types to automatically parameterize a test with all the fork supported transaction types that can create a contract.

Really nice addition! I commented a few small potenetial tweaks if you want to add them.

And also a comment about checking whether evmone could handle the empty string case on there end. My naive-ity might be underestimating C++ though
