Re: [css-houdini-drafts] [css-properties-values-api] Composition behavior of lists

Generally `composite: 'add'` becomes list concatenation and `composite: 'accumulate'` becomes component-wise addition. This matches the behavior in SVG.

For `iterationComposite`, we only allow `accumulate` because we were concerned that if you repeat an animation 1000 times doing list concatenation you'll end up with a really long list. (I think we later worked out that wasn't such a big deal, but I can't remember why.)
