Gracefully handle unknown WAL record types. (#8004) 
As we're looking to expand what's in the WAL,
having old Prometheus servers ignore the new record types
rather than treating them as corruption allows for better
upgrade/downgrade paths.

Adjust some tests accordingly, so they're still testing what they're
meant to test.
