Make the parser accept @font-face rules without font-family or src.
Fix#16165.
Also, it turns out that the CSSFontFaceRule IDL specified in the css-fonts spec is not web-compatible. Instead browsers implement a .style attribute like in CSSStyleRule: https://github.com/w3c/csswg-drafts/issues/825
This in turn requires preserving data about which descriptors were set or not (distinguishing unset from set to a value that happens to be the initial value), so this commit also makes every field `Option<_>`.

Use Servo-specific pseudo elements for anonymous box and text
<!-- Please describe your changes on the following line: -->
Use some fake pseudo elements to style servo-specific boxes in servo. Also, Since for nested inline elements non-inheritable properties are properly stored in the inline context of an inline fragment, so get
rid of them on the style using empty pseudo to do cascading.

Fix scroll root of absolutely positioned elements
Absolutely positioned elements should be given the scroll root of their
containing block and not necessarily the scroll root of their parent.
This fixes several CSS tests, though others are still failing pending a
similar fix for inherited clipping rectangles.
Fixes#13530.
