Previously, GetLockStatusData() checked all slots for every backend to gather fast-path lock data, which could be inefficient. This commit refactors it by skipping backends with PID=0 (since they don't hold fast-path locks) and skipping groups with no registered fast-path locks, improving efficiency. This refactoring is particularly beneficial, for example when max_connections and max_locks_per_transaction are set high, as it reduces unnecessary checks across numerous slots.
