Currently PowerHAL does not distinguish between system processes and
apps when deciding whether to apply universal boost. This patch
distinguishes system sessions and app sessions and ignores system ones,
making the disabling of universal boost dependent on the presence of app
hint sessions.

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.

HintManager is unique and widely used in many different components.

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.

An init trigger would restart powerhal as early as the property was
loaded and it is hopefully early than any clients would try to connect.
Also remove the obsolete restart hook with audio.

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)

The ndk_platform backend will soon be deprecated because the ndk backend
can serve the same purpose. This is to eliminate the confusion about
having two variants (ndk and ndk_platform) for the same ndk backend.

"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

To workaround b/141025174, adding support for devices without display
idle signals. Also added a property to override idle display function.
Besides the idle signal support, this CL also makes touch boost duration
tunable through several new vendor properties. It also named display
idle monitor thread and cleans out the obsolete HIDL Power HAL
implementation.
