feat(main): Add localization support

Add i18next with a custom backend to the main process to load
localization from file.

Missing localizations are written to a missing localizations file in
debug mode, but silently fall back in production mode.

We will also need to add a custom backend for the renderer process that
communicates with the main process.

(i18next-fs-electron-backend is not applicable here, because we need
localizations both in the main and renderer processes.)
