Export list of languages which will trigger language conversion

Browse source 
LanguageConverter is enabled on a per-page basis, based on the page
language and whether it implements `$lang->getConverter()`.  Export
this in siteinfo so that Parsoid knows whether it should parse
language converter markup on a given page (based on the page language).
