dev-manual, ref-manual: Created new section on initramfs
Fixes [YOCTO #7096]
We did not document how to create an initramfs image to be included
with a kernel build. Various variables sort of inferred the
knowledge. I created a new section in the "Common Tasks" section
of the dev-manual that describes how to create an initramfs image.
Also, I updated the kernel.bbclass reference section to point back
to the new "how-to" section.
Finally, I also created a bunch of cross-reference links from various
related variables back to the new "how-to" section.
