If the user wants to stop controlling uclamp and let the task inherit
the value from the group, we need a method to reset.
Add SCHED_FLAG_UTIL_CLAMP_RESET flag to allow the user to reset uclamp via
sched_setattr syscall.

If the user wants to release the util clamp and let cgroup to control it,
we need a method to reset.
So if the user set the task uclamp to the default value (0 for UCLAMP_MIN
and 1024 for UCLAMP_MAX), reset the user_defined flag to release control.
