Optimize Mutex Lock Contentions for Improved QPS in SSB Benchmark

Optimize the lock contentions for ThreadGroupStatus::mutex. The performance experiments of SSB (Star Schema Benchmark) on the ICX device (Intel Xeon Platinum 8380 CPU, 80 cores, 160 threads) shows that this change could bring a 2.95x improvement of the geomean of all subcases' QPS. #41675 (Zhiguo Zhou).
