Tests update 14.1 Legacy Tests

The recent tests changes:

From now on there would be no new test vectors in this repository and existing ones will slowly be converted into https://github.com/ethereum/execution-spec-tests. NOTE: Pyspecs doesn't cover all the vectors from this repo, but has many new vectors that are not covered in ethereum/tests
Eventually there will be only ethereum/legacytests repo with all .json tests from Frontier to Cancun.
And ethereum/execution-spec-tests will handle all the official ethereum testing vectors for all the froks.
