Request for a navigationCommited event to inform immediately about the navigation status

[whimboo]

This is a request from the Playwright folks:

Introduce an event or method to track when a navigation is committed, beyond the current DOMContentLoaded and load events, which would be useful for some client requirements (e.g., 'should return when navigation is committed if commit is specified'). We need to know immediately if the navigation has failed or succeeded.

In Puppeteer this event is named page.frameNavigated.

It's not clear right now where in the HTML spec it could hook into to accurately inform about the status of the current navigation.
