All traversal processes are like this:
1. Traverse only elements that have this restyle hint (animation-only traversal)
RESTYLE_CSS_ANIMATIONS is stripped off from restyle hints of the elements
2. Traverse all dirty elements (normal traversal)
3. Create a SequentialTask if we have updated CSS Animations properties in
the normal traversal
4. Traverse elements that need to have updated animation style as a result of 3
(second animation-only traversal)
We will set the flag when the root node of the traversal has
has-animation-only-dirty-descendants flag or has animation restyle hints.
Also we will use this flag to detect whether we need to trigger CSS transitions
or not.
It's a bit unfortunate the use separate implementations of SpecifiedUrl for Servo
and Gecko, but they're different enough at this point that I don't think it really
makes sense to try to share everything. Splitting them out has some nice
simplifications as well.
I recognize that there's still some potential correctness issues for Servo using
the resolved URI in various places where the original URI may be the right thing,
but I've got too much on my plate to look into that for now.

Before this patch, we store each computed values in a hashtable,
nsRefPtrHashtable<nsUint32HashKey, RawServoAnimationValue>, for all
KeyframeEffectReadOnly on an element, and convert the ServoAnimationValues of
the hashtable into an nsTArray<ServoAnimationValue*> and then convert
the ServoAnimationValues of the nsTArray into PropertyDeclarationBlock
in rust. This way was really inefficient.
In this patch, we store the computed values into AnimationValueMap and
convert all AnimationValue in the map into PropertyDeclarationBlock
after EffectCompositor::GetAnimationRule.

This effectively combines the discriminants of the two enums and reduces the
size of PropertyDeclaration by one word.

Make size_of tests measure stylo and reduce the size of stylo PropertyDeclarations by 16 bytes
Right now they don't, which means that we have four properties making PropertyDeclaration 16 bytes bigger than it should be.
I'm not sure if there's a better way to get these tests to run against stylo than to hoist them into the properties file, but I couldn't figure it out. This seems good enough.

Let the embedder decide if servo should follow a link or not
We want to give a chance to the embedder to handle a link itself.
Is it a problem that this will add a round trip to the main thread every time `load_url` is called?

Now that cascade() gets a Device, we can use the default computed values from
there to avoid propagating that state all over the place.
