Considering the previous uclamp.min value is the base of PID output.
Instead of:
`next_min = std::min(sUclampMinHighLimit, output);`
We should use:
`next_min = std::min(sUclampMinHighLimit, current_min + output);`
When session status entered stale state, set the uclamp to 0, but keep
the current_min. That would be helpful for boosting the heavy workload
of the first few frames.

There is no history kept in powerhint session, so let us just keep what
we have in the PID controller and let new samples settle.

1. Clean all messages before add new.
2. Insteading of using `this`, use the unique mStaleHandler sp so Looper
can hold the sp to keep the instance alive until the last message
done.

1. set uclamp.min high to 384 (from 512)
2. set uclamp.min low to 2 (from 0)
3. set kPo to 2 (from 5)
4. set kPu to 1 (from 3)
5. instead of the previous boost value, use I Error-Integral as the base
of boost value.
6. add more traces (wakeup, overtime)

"GPU completion" task inherits a high uclamp value from RenderThread.
But it's not in the ADPF thread list, so it remains a high uclamp value.
Use SetTaskProfiles("ResetUclampGrp") and
SetTaskProfiles("NoResetUclampGrp") to manage the uclamp_fork_reset for
tasks.

The patch includes:
1. Move from folder adpf to aidl.
2. Add PowerSessionManager class to maintain hint status.
And PowerHintMointor looper thread for monitoring or updating
PowerHintSession status.
3. Use PID algorithm to replace the step-wise alogrithm for cpu resource
control.
