Issue: Key events for macOS keys "rewind" and "fast forward" not received
Labels: a: text input,P2,fyi-text-input,team-macos,triaged-macos

## Steps to reproduce

Run the following app on macOS using an Apple keyboard:

```dart
import 'package:flutter/material.dart';

void main() {
  runApp(
    const MaterialApp(
      title: 'Issue reproduction',
      home: IssueApp(),
    ),
  );
}

class IssueApp extends StatelessWidget {
  const IssueApp({
    super.key,
  });

  KeyEventResult _handleKeyEvent(FocusNode focusNode, KeyEvent event) {
    print(event);
    return KeyEventResult.handled;
  }

  @override
  Widget build(BuildContext context) {
    return Focus(
      // focusNode: focusNode,
      autofocus: true,
      onKeyEvent: _handleKeyEvent,
      child: const SizedBox.expand(),
    );
  }
}
```

Then once the app is running, hit any regular key and look for the console log messages to show that the key event is getting registered.  Then try hitting the "rewind" or "fast forward" key (also mapped to F7 and F9):

## Expected behavior

You expect to receive key events for those keys. More generally, you expect to be able to register handlers for those keys in your Flutter app.

## Actual behavior

Nothing gets printed to the console, showing that the key events are not firing for those keys.
