      Make the latch analysis counters in Mutex use fetchAndAddRelaxed instead of fetchAndAdd.

      The work done in SERVER-75867 shows that even though this change might not improve the ops_per_sec performance measurements for industry benchmarks, the change reduces the time we spend incrementing the latch analysis counters on ARM.
