fixes [Expose animation parameters for the [ExpansionTile] widget](#138047)

### Description
Add `AnimationStyle` to the `ExpansionTile` widget to override the default expand and close animation.

Syntax:
```dart
        child: ExpansionTile(
          title: const Text('Tap to expand'),
          expansionAnimationStyle: AnimationStyle(
            duration: Durations.extralong1,
            curve: Easing.emphasizedAccelerate,
          ),
          children: const <Widget>[FlutterLogo(size: 200)],
        ),
```
