It seems Chromium and Webkit support offset-position in the style system but not fully use it in motion transform, e.g. Webkit bug: https://bugs.webkit.org/show_bug.cgi?id=240272.
offset-position is used for ray() function and some <basic-shape>s, but not for path() function and others. In order to improve the interop score for [motion-1], we can support offset-position in the style system first and then use other separate bugs to apply offset-position for offset-path values which need it.

Also, we make it animatable but not apply it to the motion transform for
now (so it works for getComputedStyle but doesn't have rendering result).
Per spec: https://w3c.github.io/csswg-drafts/css-values/#calc-serialize,
we tweak the WPT to let calc() serialize the percentage first, and maintain
zero-valued terms, i.e. 0%. (We are doing the same thing as
offset-anchor, so it should be fine with other browsers.)
Besides, I tweak the serialization of shorthand a little bit so we match
the implementation of WebKit.
