XRImageTrackingFeature

This OpenXRFeature configures Android XR extensions XR_ANDROID_trackables, XR_ANDROID_trackables_image, and XR_EXT_future at runtime and provides a XRImageTrackingSubsystem implementation that works on the Android XR platform.

Note: due to the dependency on XRSessionFeature, its priority must be lower than it so the feature registration happens after XrInstanceManager creation.
