The choice screen is irrelevant when debugging apps locally. `flutter run` creates a separate user profile for testing only. It doesn't touch users' browser settings.

Fixes https://github.com/flutter/flutter/issues/153972 (unless the cause of https://github.com/flutter/flutter/issues/153064#issuecomment-2305662791 happens to also prevent this fix from working).
In this PR, I've looked for all non-test call sites of `ChromeConnection.getTabs` and made sure are all wrapped in `try` blocks that handle `IOException` (`HttpException` is what we see in crash reporting, but I figure any `IOException` might as well be the same for all intents and purposes).
I plan on cherry-picking this the stable branch.
https://github.com/flutter/flutter/pull/150645 tries to shut down Chrome by sending a browser close command through a debug protocol. The webkit_inspection_protocol library used to send the command may throw a SocketException if Chrome has already been shut down.
The previous approach of killing the Chromium parent process sometimes caused leaks of child processes on Windows. The Browser.close command in the debug protocol will tell Chromium to shut down all of its processes.
This implements https://github.com/flutter/flutter/issues/132654#issuecomment-1738221257, namely:
Make `Chromium.close` more robust:
* Send `SIGTERM` and wait up to 5 seconds, if the process exited, great! Return from the function.
* If the process has not exited, then send a `SIGKILL`, which is a much firmer way to exit a process. Same as before, wait up to 5 seconds, if the process exited, great! Return from the function.
* If it still hasn't exited then give up trying to exit Chromium, just print a warning to the console and return from the function.
Bonus: a few nullability fixes and extra `-v` logging.
