Peifeng Li eed2741ae6 ANDROID: vendor_hook: add hooks to protect locking-tsk in cpu scheduler ...

Providing vendor hooks to record the start time of holding the lock, which
protects rwsem/mutex locking-process from being preemptedfor a short time
in some cases.

- android_vh_record_mutex_lock_starttime
- android_vh_record_rtmutex_lock_starttime
- android_vh_record_rwsem_lock_starttime
