Flutter web symbolication uses scope instead of name but the name in some cases if not all is better

[marandaneto]

Environment

Flutter web 3.7.x

Steps to Reproduce

Throw exception in async method.

onPressed: () async {
  await Future(() {});
  throw Exception('Test exception');
},

More context here getsentry/sentry-dart#1430 (comment)

Probably relates to dart-lang/sdk#52483 as well

Expected Result

Frame at <fn> (main.dart.js:56371:16) gets symbolicated to:

at MainApp.build.<anonymous function>(../../../lib/main.dart 25:15)

Actual Result

Frame at <fn> (main.dart.js:56371:16) gets symbolicated to:

at $async$$0(../../../lib/main.dart:25:15)

@loewenheim can we do something about this during our symbolication? special case Dart/Flutter events and read the scope instead of the name when available?
