This is useful for nova (which wants to use a gradient border around the
selected tab and right now hack around it with multiple backgrounds).
For now enable only on chrome code by default since we only support
solid borders (which is what we want anyways), and we don't support
combining it with `background-clip: text`.

Per the css-overflow propagation rule [1], 'visible' on the viewport is
interpreted as 'auto' and 'clip' is interpreted as 'hidden'. So dynamically
toggling the root element's overflow between 'visible' and 'clip' changes
the viewport's propagated scrollbar styles between 'auto' and 'hidden'.

With the TreeScopedTag + the extra tag, these end up being massive.
Compact their representation by reusing the array. Since they're dashed idents
we can just store the regular values however we want.

Note about layout.css.scrollbar-width-thin.disabled:
In the case where the pref is false (default),
```
.scrollabler { scrollbar-wdith: thin; }
.scrollable::-webkit-scrollbar { display: none; }
```
does NOT hide the scrollbars just like what Chrome does.
In the case where the pref is true,
```
.scrollabler { scrollbar-wdith: thin; }
.scrollable::-webkit-scrollbar { display: none; }
```
does NOT hide the scrollbars either, the width of scrollbar is rendered
as if it's 'auto`.

Parse these two longhand properties and do serialization for them.
We use two different structs to wrap `AnimationRangeValue` because their
`parse()` and `to_css()` are slightly different.
Besides, these properties should be applied to ::marker and we will add
them in the following patch.
