Add auto restriction for excessive background

If it is excessive bg anomaly and auto restriction is on, then
restrict the anomaly in receiver and store it in database.

Also in this cl we move the anomaly logic to a JobService, so all
works are done in a background thread and won't interfere the main
thread.

Will add auto restriction test once robo framework is updated(b/73172999)
