Create a `blockchain_engine_tests` test runner

[jochem-brouwer]

When consuming fixtures, we are currently semi-directly able to run the state/blockchain/tx tests. (Sample fixtures: https://github.com/ethereum/execution-spec-tests/releases/tag/pectra-devnet-6%40v1.0.0)

Steps:

• Download the fixtures release and unzip it. This currently yields 4 folders:
  • blockchain_tests
  • state_tests
  • transaction_tests
  • blockchain_tests_engine
• Move the state_tests and blockchain_tests inside ./packages/ethereum-tests/fixtures (create folder if not there)
• Run state tests: cd ./packages/vm && npm run test:state -- --dir=../fixtures --fork=Prague
• Run blockchain tests: cd ./packages/vm && npm run test:blockchain -- --dir=../fixtures --fork=Prague
• Move the transaction_tests inside ./packages/ethereum-tests/TransactionTests
• Run transaction tests: cd ./packages/tx && npx vitest run ./test/transactionRunner.spec.ts

We currently have no way to run blockchain_tests_engine.

This should be added to the client.

Additionally it would be nice to have a handy tool to directly consume the unzipped fixtures. This should also extract ALL forks in the fixtures and run these all. (For the linked fixtures, Prague is the main fork to run against, but there is also the transtition tests CancunToPragueAtTime15k)
