Add action active check for anomaly action.

This cl adds the action active check for the following actions:
1. ForceStopAction: check whether app is stopped
2. BackgroundActivityAction: check whether background activity
is turned on

If related action is not active, we won't report anomaly
to users. Future cl will add active check for bluetooth anomaly.
