This commit extracts the tuple-building logic from pg_stat_get_lock() into a new static helper pg_stat_lock_build_tuples(). This is in preparation for a follow-up patch, to add support for backend-level lock stats, which will reuse the same helper. This change follows the pattern established by pg_stat_io_build_tuples() for IO stats and pg_stat_wal_build_tuple() for WAL stats.
