Add UsageStatsQueryHelper to People Service

It processes these UsageStats events:
- SHORTCUT_INVOCATION
- NOTIFICATION_INTERRUPTION
- LOCUS_ID_SET
- ACTIVITY_PAUSED/STOPPED/DESTROYED

The in-app conversation is counted from the LOCUS_ID_SET event to the
next LOCUS_ID_SET event, or the associated Activity is
paused/stopped/destroyed.
