add berlin tx support

[GregTheGreek]

Description

Adds berlin tx support.

Notes about tests:
Since the new transaction type changes how the transactions are RLP'd some of the messages hashes needed to be updated. Only test cases with error: false (or omitted completely) will run successfully in the first place, and thus tests with error: true did not need to be updated.

closes #3963
closes #4012 (supersedes)

The dist/ files were updated, but should only be updated upon release, otherwise, it looks good!
