Add 'miniresolver' UI for cross-profile single app resolution.

When the current profile only has web browsers and the other profile has
a single non-browser app to handle the given intent, simplify the
resolver UI to present the user with a yes/no question about how to
handle.

Canonical example of this is "clicking a youtube link in your work
profile".
