title bar: Adjust the onboarding banner component API (#27455)

This PR encapsulates the layout building of the Onboarding Banner
component inside of it, allowing to, at the call site, just pass an
icon, title, and subtitle. The `subtitle` parameter, by default, uses
the `Introducing:` label, which I think will be the one we'll use most
of the time for this specific component.

Release Notes:

- N/A
