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.

* Fix bug with WAL watcher and Live Reader metrics usage.
Calling NewXMetrics when creating a Watcher or LiveReader results in a
registration error, which we're ignoring, and as a result other than the
first Watcher/Reader created, we had no metrics for either. So we would
only have metrics like Watcher Records Read for the first remote write
config in a users config file.

Add back Windows CI, we lost it when tsdb was merged into the prometheus
repo. There's many tests failing outside tsdb, so only test tsdb for
now.
