Make transform perspective reject negative lengths.
<!-- Please describe your changes on the following line: -->
`transform: perspective(-10px)` is invalid per spec. This patch prevents negative values from being parsed. There is an issue if zero should be allowed: https://github.com/w3c/fxtf-drafts/issues/126

Remove servo_url dependency for geckolib
It seems mod attr is not used for geckolib at all, and that is the only place where servo_url is still referenced for geckolib, so we can just remove it.

Reduce cloning of FrameState
<!-- Please describe your changes on the following line: -->
This uses `kmerge` from itertools to construct the jsh future and past iterators without having to do a collect/sort. This allows us to reduce cloning of `FrameState`.

The computed value of word-spacing is T(pub Option<LengthOrPercentage>),
the computed value of letter-spacing is similar to this, T(pub Option<Au>).
It would be nice to have re-usable macro for these kind of struct.

animation_type takes following values:
animation_type="none" for non-animatable properties
animation_type="normal" for animatable properties
animation_type="discrete" for animatable but discrete type of animations
We use string value to distinguish the case where no animation_type is
specified.
animation_type="discrete" will be used in a subsequent patch to make a property
animatable as discrete type.
Hoist possibly_expired_animations into CurrentElementInfo
The current mechanism requires threading a lot of this state through a bunch of
callsites that are several layers of abstraction above the code that actually
uses this vector (which is only compiled for servo). Putting it in
CurrentElementInfo gets it nicely out of the way.

This is necessary in order to make the computation of eager pseudos depend on
the primary ComputedValues, which we want to do for ::first-letter/::first-line.
This also fixes a bug where the behavior of EagerPseudoStyles::is_empty was reversed
in both the implementation and the callsite.

Use real clips when generating scroll roots
This is the first step toward removing inherited clips in favor of
scroll roots for handling overflow and CSS clipping. This will allow us
to more easily handle elements that should not be clipped. While we are
still using inherited clips here, we now properly clip some types of
content that wasn't clipped before.

This simplifies things by avoiding the computation of MatchResults when we
don't need them.
We continue to compute rule_nodes_changed, even though we don't use it
for the moment, since we will need it soon for various incremental restyle
optimizations.

Recent change in bug 1277709 makes ThreadSafeAutoRefCnt start using std::atomic, which somehow doesn't not have #[derive(Debug)] on Windows, which makes all objects which includes ThreadSafeAutoRefCnt to stop having #[derive(Debug)]. This breaks stylo build on Windows.
By adding it as an opaque type, std::atomic would derive Debug again.
Two functions added in this patch get progress value from ComputedTiming
or get the position in a given AnimationPropertySegment.
Without these FFIs, we need to expose Maybe<> and Nullable<> and handle
them in Rust.
When we compose style for a given nsCSSPropertyID in the case where
we have no specified values in target keyframe, we use this AnimationValue
for composition as if it's specified.
