Re: [csswg-drafts] [css-animations-2] Move scroll and event animation triggers to independent namespace (#12336)

One option for a syntax could be making these 2 events as functions that accept insets, or ranges, or both.
Maybe even simplify them to something different (going wild here), like take a number as a threshold, kind of like `IntersectionObserver`s:

- `viewenter(0.5)`: would be like `view()` with `entry 50% exit 50%`.
- `viewleave()`: could default to `0` which means `view()` with `cover`.

We could also add `insets` with a separator if needed.
Note the `axis` can be dropped entirely since this isn't required to compute a progress value, but rather specify a rect.
