Update slashing protection interchange to v5 (#1816)
## Proposed Changes Update the slashing protection interchange format to v5 in preparation for finalisation as part of an EIP. Also, add some more tests and update the commit hash for https://github.com/eth2-clients/slashing-protection-interchange-tests to include the new generated tests.
