[flutter_tools] more debugging for timeouts in break_on_framework_exceptions test (#125584) 

Better debugging to investigate: https://github.com/flutter/flutter/issues/125241

When the `test/integration.shard/break_on_framework_exceptions_test.dart` test times out, log out verbose logging to give clues as to why it did not complete.

From one local run it looks like the test runner is failing to load a test file (when I checked the path locally, the file was there, and re-running the `flutter test ...` invocation succeeded--in that the app threw an exception):

```
