For now, only impls for types like in style::values::generics can be derived.
This also needed a few ToComputedValueAsSpecified impls that I would like to
replace by some #[to_computed_value(clone)] attribute, but I think it is ok
to keep it like this for now.

style: Move all the style sharing code outside matching.rs
This is just a code health change. I want to move it away to keep matching.rs as
simple as possible.

stylo: Bug 1334036 - Enable animations running on compositor.
These are interdependent patches of Bug 1334036, which enables off-main thread animations. We add one FFI to get the property id set which overriding animations, so we can make sure the cascade result is correct for off-main thread animations.

- [X] These changes do not require tests because we support off-main thread animation only on Gecko, and there are enough test cases there.

In some cases, e.g. mouse event, we need to request an animation-only restyle
to force flush all throttled animations when we handle an event with
coordinates. This restyle shouldn't trigger a normal restyle, and add a
different traversal flag, TraversalRestyleBehavior::ForAnimationOnly, to check.
If we add/remove important rules, we may need to update a list of all important
rules (in Gecko) which overrides animation properties. Therefore, we need to
set a flag if we update the primary rules which includes important ones.
If we have animations on this element, we update its effect properties, and
also send a task to update cascade results.
Calling get_properties_overriding_animations() might cases some impact
on performance because we need to walk the rule tree, so if possible, we could
just store this set into TNode to avoid finding the properties for both old
and new rules each time. This could be a future work if necessary.
Make font-stretch animatable.

We add one FFI, Servo_GetProperties_Overriding_Animation, which calls
StrongRuleNode::get_properties_overriding_animations() to get a LonghandIdSet,
which may override animation properties running on compositor.
