Send power hints from surfaceflinger using the PowerAdvisor

Have SurfaceFlinger send timing hints to the PowerHAL to help meet the frame deadline and dynamically scale clock frequency for different workloads.

This patch additionally refactors a few closely related parts of the PowerAdvisor, and expands the logging there for this feature.

To enable the power hint session, use:
adb shell device_config put surface_flinger_native_boot AdpfFeature__adpf_cpu_hint true
