XRMultimodalFaceFeature

This feature exposes multimodal face tracking capabilities provided by XR_ANDROID_face_tracking_data_source extension.

It's a supplement to Unity OpenXR Android XR's Android XR: AR Face feature which integrates XRFaceSubsystem and exposes current tracking modality via ARFaceManagerExtensions.TryGetFaceTrackerMode(ARFaceManager, out XRFaceTrackerMode).

If this feature is not enabled, ARFace will default to image-only face tracking, which may not be supported on all devices.
