Grant CAPTURE_AUDIO_OUTPUT permission for trusted process

HotwordDetectionService is an isolated service which ordinarily
cannot hold permissions, so we dynamically override the permissions
check based on the currently bound HotwordDetectionService.

We have a similar change to grant RECORD_AUDIO and CAPTURE_AUDIO_HOTWORD
permissions to HotwordDetectionService before.
