sm6375-common: power-libperfmgr: ADPF: use PID algorithm to control cpu resource

Browse source 
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.

Test: build, boot to home, trace analysis
