Add missing RequiresPermission annotations in BluetoothHidHost and
BluetoothMap APIs, disallow null device input for setConnectionPolicy,
getConnectionPolicy, and getConnectionState in BluetoothHidHost, and
BluetoothMap implements AutoCloseable, its close() method is public, and
utilizes a CloseGuard.
