Previously these tests were setting the test-only `KEY_CONTROLLER` bundle value to the prod value of `MediaController.KEY_MEDIA_NOTIFICATION_CONTROLLER_FLAG`, which is a bit confusing because this is intended to be used as a `Bundle` **key** (for a boolean value), and not a value itself. Instead this CL creates a test-only value that can be used by `RemoteMediaSession` and related test-only friends to indicate that something (e.g. error or extras) should only be set on the notification controller. This CL also changes the logic in `MediaSessionProviderService` to avoid needing to special-case checking for this controller key. PiperOrigin-RevId: 641939283
