The page is hidden behind the flag imeOptionsInSettings.
Currently the page is only a dummy page following the spirit at
https://docs.google.com/presentation/d/1jdefmoq3c0xXt8_oD19819FKFw5BFKp9gPdr2DegcRQ/edit#slide=id.g8514a6facb_0_313

The content of the new page will soon be changed in the next CLs, and
the text on the page will be generated in the js code. So I will do the
i18n later. For now I added TODO(i18n) explicitly in UI so I won't
forget about i18n issue.
