core-image-tiny-initramfs: Add and image creating image artifacts only 

Add an image that simply creates image artifacts using
image-live-artifacts support instead of creating an actual image.

The image artifacts can then be subsequently assembled by an external
tool such as wic to create an actual image.

This eliminates redundant image creation when using such tools.

# Simple initramfs image artifact generation for tiny images.
DESCRIPTION = "Tiny image capable of booting a device. The kernel includes \
the Minimal RAM-based Initial Root Filesystem (initramfs), which finds the \
first 'init' program more efficiently. core-image-tiny-initramfs doesn't \
actually generate an image but rather generates boot and rootfs artifacts \
into a common location that can subsequently be picked up by external image \
generation tools such as wic."
