Remove SQL_LANGUAGES, which was eliminated in SQL:2008, and SQL_PACKAGES and SQL_SIZING_PROFILES, which were eliminated in SQL:2011. Since they were dropped by the SQL standard, the information in them was no longer updated and therefore no longer useful. This also removes the feature-package association information in sql_feature_packages.txt, but for the time begin we are keeping the information which features are in the Core package (that is, mandatory SQL features). Maybe at some point someone wants to invent a way to store that that does not involve using the "package" mechanism anymore.
