distro_tracking_fields: move to meta-yocto as seperate files
We are going to take a phased approach of breaking up the
distro_tracking_fields, first is to remove it from oe-core,
then create new files in meta-yocto. We are doing this because
the distro_tracking_fields is getting unweildly and some of
the data can be part of a burn down list instead continually
stored, thus it will get split up.
