Add missing intents to protected broadcasts

Intents broadcasted by the Bluetooth stack need to be added to protected
broadcasts else they complain with errors in the log since Bluetooth is
considered a system process. A few of these intents, especially AVRCP
intents were missing in the list.

Bug: None
Test: Verified errors don't show up after introducing the intents while
playing on a sink device.
