Tx: add Ethereum/tests TransactionTests

[jochem-brouwer]

Ethereum/tests has a TransactionTests directory: https://github.com/ethereum/tests/tree/develop/TransactionTests

It would be nice to add these tests - it is especially interesting to see if we invalidate all invalid transactions.

We are running them in the tx package :) see https://github.com/ethereumjs/ethereumjs-monorepo/blob/master/packages/tx/test/transactionRunner.ts#L32

Oh great, fake news 😂

I was not aware that we were running those! Will close.
