documentation: Purged the YP Quick Start references from YP set

The original Yocto Project Quick Start is being retired for the
YP 2.5 release (sumo).  I have purged all the various references
from the YP manual set and replaced them with references to the
appropriate doc.  The references were mainly into the YP
dev-manual for setting up the host or for building an image.
There were a few references into the new "Yocto Project Quick
Build" document for overviewing manual-type references.
