Implement radial gradients
<!-- Please describe your changes on the following line: -->
This PR passes the `radial-gradient` function down from CSS parsed properties to webrender. It currently lacks tests but the examples from MDN and some other tests work fine. Probably there are some wpt tests I can enable?

stylo: Bug 1357357 - Make the parser of transition-property match the spec.
These are interdependent patches of Bug 1357357. We add one more arm, TransitionProperty::Unsupported, which stores the string of non-animatable, custom, or unrecognized property, so we can parse these kinds of properties and serialize them correctly. This is necessary because we need to start transitions even though some transition-properties are non-animatable, custom, or unrecognized.

1. We add a new arm to TransitionProperty, TransitionProperty::Unsupported,
which contains an Atom, so it's better to remove the Copy trait from
TransitionProperty.
2. TransitionProperty::Unsupported(Atom) represents any non-animatable, custom,
or unrecognized property, and we use Atom to store the ident string for
serialization.

* Add to_computed method to calculate `calc()` value with parent size,
if parent container size is `None`, the result will be `None`.
* Add from_option method for `MaybeAuto`, to construct from
`Option<Au>`.
* Update some test case.
layout: Force reflow in the sequential fallback of block format context
When reflowing a block format context during the inorder traversal,
propagate restyle damage manually to its children since they were
already reflowed. Also, test the border box to see if it can fit into
floats according to CSS 2.1 § 9.5.

propagate restyle damage manually to its children since they were
already reflowed.
Instead of passing down a complex clipping region to each item, used
shared clipping to handle overflow:hidden and CSS clips. In addition to
being more efficient, this should also fix quite a few issues related
to absolutely positioned elements.
One existing reftest is slightly modified to avoid tickling a quirk
with the way that WebRender rasterizes masks. We are working out how to
best express these combined masks with the API or need to. The change
does not affect the original subject of the reftest.
Fixes#13109.
Fixes#10151.
Fixes#7575.
Fixes#8074.
Fixes#8780.
This includes the new border code path for simple (solid) borders.
This gives much higher quality border rendering, including proper
support for elliptical border segments.
The quality on https://github.com/servo/servo is noticeably improved.
style: Do not immediately convert absolute specified lengths
<!-- Please describe your changes on the following line: -->
This PR aims to solve issue #15729. I tried to follow the recommendations there as much as possible.
This is my first attempt at contributing to Servo, so this will probably need a lot of input, although I'm eager to make it as polished as possible.
- The base inaccuracy issue seems solved, as can be easily verified with the `console.log` based example in the issue.
- Very basic unit tests were added.
I have doubts mainly about the right way to represent these new enum variants for the various length units:
1. With new enum variants in `NoCalcLength` *and* newtypes (current solution)
2. With a `NoCalcLength::Absolute` variant that contains a new `AbsoluteLength` enum, but without newtypes
3. Same as solution 2 but with newtypes
- I mostly cared about unit tests until now but will investigate other types of tests
- Tests to check the clamping
- Write a proper commit message
Thanks for your time and feedback :)

The NoCalcLength::Absolute variant has been rewritten to accommodate
other units than Au with the new AbsoluteLength enum. This avoids loss
of precision for some operations.
The conversion from floating point absolute lengths to integer
application unit values adopts the same clamping limits as Gecko.
Implement serialization for transform functions.
Preserve more information from transform function parsing.
Preserve angle unit while parsing.
Simplify SpecifiedMatrix.
Use the write! macro for formatting with a helper called Css.
Implement ToCss for &T if T implements ToCss.
Add some tests and update others.

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<_>`.

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.
Correct viewport test references
These references were using an incorrect value for the expected
container width. Now that WebRender is no longer clipping to stacking
context boundaries the rendered width is correct (100% of viewport
width = 240px).
