Issue: Default foreground color animation duration doesn't apply on icon of `Button` widgets
Labels: framework,a: animation,f: material design,has reproducible steps,team-design,found in release: 3.27,found in release: 3.29

### Steps to reproduce

1. Create a new Flutter project
2. Use the `ElevatedButton.icon()` widget and specify an `icon` and `label` widget
3. Override the `style` property to the following:
   ```dart
   style: ButtonStyle(
     foregroundColor: WidgetStateProperty.resolveWith<Color?>(
       (states) => states.contains(WidgetState.hovered)
           ? Colors.white
           : Colors.white24,
     ),
   ),
   ```
4. Notice the different hover animation duration on the icon and the label text (the animation doesn't seem to apply at all on the `icon`).

### Expected results

Same default foreground color hover animation duration ([`kThemeChangeDuration`](https://api.flutter.dev/flutter/material/kThemeChangeDuration-constant.html)) on both the icon and the label.

### Actual results

Default foreground color animation duration doesn't apply on the icon at all, only applied on the label widget which make it look buggy (see the screen recording attached).

                icon: Icon(Icons.star, size: 50),
                label: Text('Button', style: TextStyle(fontSize: 36)),
                onPressed: () {},
                style: ButtonStyle(
                  foregroundColor: WidgetStateProperty.resolveWith<Color?>(
                    (states) => states.contains(WidgetState.hovered)
                        ? Colors.white
                        : Colors.white24,
                  ),
                ),
              ),
            )
          ],
