This is a pain: languages_model depends on prefs and prefs_types, and prefs
depends on prefs_types, so why don't these dependencies propagate without me
having to list them here?

+          'languages_model.js',

Same thing here: adding languages_model.js seems to make languages_model.js be
compiled twice. But if I remove it, languages_page can't compile:

## src/chrome/browser/resources/settings/languages_page/languages_page.js:37:
ERROR - Bad type annotation. Unknown type LanguagesModel
##      * @type {(LanguagesModel|undefined)}
##                ^

## src/chrome/browser/resources/settings/languages_page/languages_page.js:52:
