bitbake: Add description into the cache and clean up cache duplication

With the addition of new cache domains, the summary, license and section
information is no longer requred in the core cache since its only used by
the hob UI. This patch removes the duplicated entries.

It also adds the DESCRIPTION field to the cache for the benefit of hob2.
