Flutter IntelliJ opens devtools in the default browser instead of chrome

IntelliJ users that do not have Chrome set as their default browser have Dart DevTools launch in a browser that does not support Dart DevTools.

The Dart DevTools server now supports launching DevTools in chrome and VSCode users it to launch web browsers. We should use this functionality from IntelliJ as well or use existing IntelliJ functionality to launch Chrome.

A Mac user I was helping debug had Safari as their default value so had to copy and paste the URL from Safari to Chrome each time they launched DevTools fro IntelliJ.
