feat(completion): add the prefix, date and mimetype vocabularies

Keywords are syntax and stay untranslated; the descriptions beside them are
prose and go through tr().

The tables are free functions with no QObject to inherit tr() from, so the
file declares a VocabularyStrings context with Q_DECLARE_TR_FUNCTIONS rather
than borrowing QObject::tr, which would file every string under the QObject
context.
