Liujie Xie 05b5ff11ad ANDROID: vendor_hooks: Add hooks for mutex and rwsem optimistic spin ...

These hooks help us do the following things:
a) Record the number of mutex and rwsem optimistic spin.
b) Monitor the time of mutex and rwsem optimistic spin.
c) Make it possible if oems don't want mutex and rwsem to optimistic spin
for a long time.
