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,
```

This PR adds `AnimationSheetRecorder.dispose`, which disposes all the images generated by the recorder, eliminating leaks.

Fixes test/animation/animation_controller_test.dart in #85160

Problem:
The test 'animateTo can deal with duration == Duration.Zero' was failing with the following error:

Expected: <0>
Actual: <5>
Expected no animation.
package:test_api expect
package:flutter_test/src/widget_tester.dart 484:3 expect
test/animation/animation_controller_test.dart 511:5 main.

Following line finds 5 transientCallbacks scheduled, while expecting zero, if shuffled with seed 123:

expect(SchedulerBinding.instance!.transientCallbackCount, equals(0), reason: 'Expected no animation.');

This is caused by some other test leaving transientCallbacks scheduled.

Fix:
By disposing the AnimationController after each test, the transientCallbacks get cleaned up.
I chose to dispose all controllers in every test, to make sure there is no risk of leaks.
