Add image-oci-docker.bbclass that converts OCI image archives to docker-archive format using skopeo-native. This produces a tar that can be loaded directly with `docker load -i` without requiring skopeo on the host. Signed-off-by: Shreejit C <shreejit.c@emerson.com>

Summary of Changes
This adds a new image-oci-docker bbclass that converts the OCI image archive produced by image-oci into docker-archive format using skopeo-native. The resulting .docker.tar can be loaded directly with
docker load -i— no host-side tooling (skopeo, Dockerfile, etc.) is required.Both nilrt-slim-container and nilrt-runmode-container now produce a .docker.tar artifact alongside the existing OCI tar.
