In service of https://github.com/flutter/flutter/issues/146879. Please see https://github.com/flutter/flutter/issues/146879#issuecomment-2118629953.

In summary, when the test flakes, `onRunnable` is not completing despite the VmService object receiving an `IsolateRunnable` event. 

This PR adds some logging code to print all events received inside of `FlutterVmService::runInView`.
