Add AnomalyConfigReceiver

This receiver receives the following intent:
1. android.app.action.STATSD_STARTED
2. android.intent.action.BOOT_COMPLETED

Also it does:
1. Check whether to upload/update config(future cl)
2. Send PendingIntent to StatsManager

Bug: 72385333
Test: Will add robo test once robo framework is updated(b/73172999)
