Add container registry support for Yocto container workflows:
- container-registry.bbclass with helper functions
- container-registry-index.bb generates helper script with baked paths
- docker-registry-config.bb for Docker daemon on targets
- container-oci-registry-config.bb for Podman/Skopeo/Buildah targets
- IMAGE_FEATURES container-registry for easy target configuration
