Added getNeverTranslateLanguages to LanguageHelper

This CL adds the translate_prefs function "getNeverTranslateLanguages"
(implemented here:
https://chromium-review.googlesource.com/c/chromium/src/+/2744619) to
the frontend's languageHelper.

This method will be used in future CLs as part of the Language Settings
Redesign for Desktop.
