[Reland] Introduce AnimationStyle (#138721)
This PR introduces `AnimationStyle`, it is used to override default
animation curves and durations in several widgets.

fixes [Add the ability to customize MaterialApp theme animation
duration](https://github.com/flutter/flutter/issues/78372)
fixes [Allow customization of showMenu transition animation curves and
duration](https://github.com/flutter/flutter/issues/135638)
fixes [`AnimationStyle.noAnimation` needs to replace `AnimatedTheme`
with just `Theme` in the
`MaterialApp`](https://github.com/flutter/flutter/issues/138618)

Here is an example where popup menu curve and transition duration is
overridden:

```dart
          popUpAnimationStyle: AnimationStyle(
            curve: Easing.emphasizedAccelerate,
            duration: Durations.medium4,
          ),
```

Set `AnimationStyle.noAnimation` to disable animation.
```dart
    return MaterialApp(
      themeAnimationStyle: AnimationStyle.noAnimation,
```
