1. Pull out TextClassifierImpl.LabeledIntent to LabeledIntent.
2. LabeledIntent.resolves takes a TitleChooser object, which
allow custom logic like "if the resolved app is a browser, use
title_with_entity. Otherwise, use title_without_entity".
If TitleChooser is not set, the default behavior is to use
title_with_entity if provided, use title_without_entity otherwise.
3. For classifyText, we use a TitleChooser that always return
title_without_entity. So no behavior change in classifyText.
4. If custom titleChooser returns null, fallback to use the default
titleChooser.
