internal/postgres: new way to get latest major version

Add DB.getLatestMajorVersion2, which uses the new series_path and
deprecated columns of latest_module_versions to get latest major
version information.

The function is not hooked up or tested yet, but it demonstrates how
we'll use the new columns.

For golang/go#43265
