Updates a few chrome/ui classes for compatibility with ephemeral Guest
profiles. Ephemeral guest profiles are not off-the-record and cannot
open an Incognito window or have bookmarks, but they have history
and Recent Tabs menu, and Clear Browsing Data option.

Please see go/guest-on-disk for more context.
