Add profiling feature based on new event implementation.

TODO:
In opencl 2.0, a new profiling item called CL_PROFILING_COMMAND_COMPLETE
is imported. It means that we need to record the time stamp of all the
child events created by the "Kernel enqueing kernels" feature finish.
This should be done after the "Kernel enqueing kernels" feature enabled.

V2:
Update event time stamp before inserting to queue thread, avoid MT issue.

V3:
Fixup overflow problem.

V4:
Fixup overflow to 0xfffffffffffffffff problem.
Just take ownership and release event lock when call the update timestamp
function. The update timestamp function may have block system call can
should not hold the lock to call it.
