Michael Sproul e4cbdc1c77 Optimistic sync spec tests (v1.2.0) (#3564) 
## Issue Addressed

Implements new optimistic sync test format from https://github.com/ethereum/consensus-specs/pull/2982.

## Proposed Changes

- Add parsing and runner support for the new test format.
- Extend the mock EL with a set of canned responses keyed by block hash. Although this doubles up on some of the existing functionality I think it's really nice to use compared to the `preloaded_responses` or static responses. I think we could write novel new opt sync tests using these primtives much more easily than the previous ones. Forks are natively supported, and different responses to `forkchoiceUpdated` and `newPayload` are also straight-forward.

## Additional Info

Blocked on merge of the spec PR and release of new test vectors.

Consensus Specification Tests

This crate parses and executes the test vectors at ethereum/consensus-spec-tests.

Functionality is achieved only via the $ cargo test --features ef_tests command.

Running the Tests

Because the test vectors are very large, we do not download or run them by default. To download them, run (in this directory):

$ make

Note: this may download hundreds of MB of compressed archives from the ethereum/consensus-spec-tests, which may expand into several GB of files.

If successful, you should now have the extracted tests in ./consensus-spec-tests.

Run them with:

$ cargo test --features ef_tests

The tests won't run without the ef_tests feature enabled (this is to ensure that a top-level cargo test --all won't fail on missing files).

Saving Space

When you download the tests, the downloaded archives will be kept in addition to the extracted files. You have several options for saving space:

  1. Delete the archives (make clean-archives), and keep the extracted files. Suitable for everyday use, just don't re-run make or it will redownload the archives.
  2. Delete the extracted files (make clean-test-files), and keep the archives. Suitable for CI, or temporarily saving space. If you re-run make it will extract the archives rather than redownloading them.
  3. Delete everything (make clean). Good for updating to a new version, or if you no longer wish to run the EF tests.
