contention profiler是否支持pthread_wrlock

看了两个实现，pthread_wrlock是用pthread_mutex_lock实现的，所以contention profiler应该也支持pthread_wrlock的吧？

Start by reading the contention profiler entry points and compare their handling with the two referenced pthread_rwlock_wrlock.c implementations. Determine whether pthread_wrlock is already covered, then add or verify coverage with a focused contention-profiler test; done means the supported behavior is demonstrated and documented by the test.
