wic-image-minimal: add wic image recipe and .wks

Added example of recipe and .wks file to create partitioned image.

This image is using quite complex partitioning scheme.
It uses its own rootfs to populate two partitions in two different ways.
It also uses core-image-minimal rootfs to populate another partition.

This is how wic reports about artifacts used to create this image:
  ROOTFS_DIR: tmp/work/qemux86_64-poky-linux/wic-image-minimal/1.0-r0/rootfs
  ROOTFS_DIR["/core"]: tmp/work/qemux86_64-poky-linux/core-image-minimal/1.0-r0/rootfs
  ROOTFS_DIR["/backup"]: tmp/work/qemux86_64-poky-linux/wic-image-minimal/1.0-r0/rootfs
  BOOTIMG_DIR: tmp/sysroots/qemux86-64/usr/share
  KERNEL_DIR: tmp/deploy/images/qemux86-64
  NATIVE_SYSROOT: tmp/sysroots/x86_64-linux
