Update spec code for compliance with spec v1.7.0-alpha.3: https://github.com/ethereum/consensus-specs/releases/tag/v1.7.0-alpha.3
The actual consensus changes are minimal. There are few more changes that are only relevant to fork choice or P2P validation that we will pick up in future PRs.
The change "Ignore beacon block if parent payload unknown" is currently covered in a hacky way by `load_parent` and can be improved once we have fork choice.
The change "Add parent_block_root to bid filtering key" is relevant to bid gossip validation, which we don't have at all in unstable yet.

Update the EF spec tests to v1.6.0-beta.1
There are a few new light client tests (which we pass), and some for progressive containers, which we haven't implemented (we ignore them).

This PR adds the ability to download [nightly reference tests from the consensus-specs repo](https://github.com/ethereum/consensus-specs/actions/workflows/generate_vectors.yml). This will be used by spec maintainers to ensure that there are no unexpected test failures prior to new releases. Also, we will keep track of test compliance with [this website](https://jtraglia.github.io/nyx/); eventually this will be integrated into Hive.
* A new script (`download_test_vectors.sh`) is added to handle downloads.
* The logic for downloading GitHub artifacts is a bit complex.
* Rename the variables which store test versions:
* `TESTS_TAG` to `CONSENSUS_SPECS_TEST_VERSION`.
* `BLS_TEST_TAG` to `BLS_TEST_VERSION`, for consistency.
* Delete tarballs after extracting them.
* I see no need to keep these; they just use extra disk.
* Consolidate `clean` rules into a single rule.
* Do `clean` prior to downloading/extracting tests.
* Remove `CURL` variable with GitHub token; don't need it for downloading releases.
* Do `mkdir -p` when creating directories.
* Probably more small stuff...
