Fix the @RequiresPermission annotation.

We initially were using PACKAGE_USAGE_STATS permission to guard
the API BroadcastOptions.recordResponseEventWhileInBackground()
but changed it's implementation to use the new
ACCESS_BROADCAST_RESPONSE_STATS permission later but didn't update
the annotation to specify the new permission.
