[gnome-continuous-yocto/gnomeostree-3.28-rocko: 4373/8267] image-wic: move wic code to image-wic.bbclass



commit 02dafba6ed8ebc718a4f513455fc034444543301

    image-wic: move wic code to image-wic.bbclass
    
    There is a lot of wic code in image.bbclass and image_types.bbclass
    Having all code separated in one file should make it more readable
    and easier to maintain.
