This pull request aims to consolidate duplicated logic in the animation controller library.

A private field has been added to AnimationBehavior:

enum AnimationBehavior {
  normal,
  preserve;

  bool get _enableAnimations => switch (this) {
    normal => !SemanticsBinding.instance.disableAnimations,
    preserve => true,
  };
}

I'll make comments to describe the other changes.

I'm very happy with the improvement from #150727!
@gnprice if you're able to take a look here that'd be great, or if you don't have the bandwidth that's totally fine :)

This was designed as an enum so we could add additional behaviors later. enableAnimations pretends that it is just a boolean, which kinda defeats the purpose of that. If we add another value to AnimationBehavior we want the analyzer to tell us all the places we need to update with new behavior.

That's fair. I could get rid of the getter, or it could be private (then in the future we could change it up without worrying about breaking people).

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.
