Add exemption cases for app background restrictions 

For the high background current drains and long-running FGS, exempt
idle allowlisted apps, companion device apps, device owner apps, etc.
Additionally, we're also exempting/setting a higher threshold for
the apps with long-running media sessions, media/location FGS,
bg location permissions.

Meanwhile, the durations that apps spent on TOP state will be excluded
from all these accounting.
