Re: [csswg-drafts] [css-view-transitions-2] Creating 'classes' of transition groups (#8319)

After internal sync, proposing the following syntax:
```css
/* To specify a class */
.box { view-transition-class: box thing }

/* To style a pseudo-element based on a class */
::view-transition-group(.box | .box.thing | this-box.thing ...) 
```
- This can apply also to `::view-transition-old`, `::view-transition-new`, `::view-transition-image-pair`
- Classes serialize together with the names in the cross-document case.
- Alternative considered: `::view-transition-group(*).box`, but it feels foreign, and creates an expectation that `.box` would also work.

In the future we can perhaps use a shorthand like `view-transition-name: this-box.any-box` (or some such).
