Transaction signing is something that happens in a lot of places - this PR introduces primitives for transaction signing in transaction_utils such that we can use the same logic across web3/eth1/etc for this simple operation.
transaction_utils also contains a few more "spec-derived" helpers for working with transactions, such as the computation of a contract address etc that cannot easily be introduced in transactions itself without bringing in dependencies like secp and rlp, so they end up in a separate module.
Finally, since these modules collect "versions" of these transaction types across different eips, some tests are moved to follow the same structure.
