SDK needs a feature gate for logging

[antoine-infinity]

I had to downgrade the SDK version because version 6 is constantly spamming my Meta Quest console. Wave SDK logs are irrelevants when the XR Loader is not enabled in Unity.

Has seen here in ViveWaveSelfTracker.cs in the OnUpdate method, there is no feature gate or nothing to effectively hide the logs (even with the log flags option in the Wave Settings).

        public void OnUpdate()
        {
            if (Application.isEditor || !Application.isPlaying) { return; }

            logFrame++;
            logFrame %= 300;
            printIntervalLog = (logFrame == 0);

            if (!InputDeviceTracker.IsAvailable())
            {
                if (printIntervalLog) { sb.Clear().Append(LOG_TAG).Append("OnUpdate() No tracker connected."); DEBUG(sb); }
                return;
            }
           ...

Had to downgrade because it is very annoying to search through the sea of Wave logs on my quest to get to my actual logs.
