WIP: Split --with-help=html packages into non-locale and per-locale

...in preparation of packaging the per-locale data properly.

non-locale: GeneratedPackage_html_media
            Package_html_dynamic
            Package_html_static

per-locale: GeneratedPackage_html_lang_generated
            Package_html_lang

This is the core part of a change that spans core and helpcontent2.
