When we have created incognito profiles managed by DevToolsBrowserContextManager
and did not explicitly close them before shutdown, we keep these profiles and
their browser windows open. This leads to forceful renderer process terminations
and crash notifications shown to the user.

To fix this, we manually close all browser windows when original profile is gone.
