Refactor pg_stat_get_lock() to use a helper function
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.
