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.
From https://bugzilla.mozilla.org/show_bug.cgi?id=1347719
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.

Add support for skipping display fixup for pseudos.

While we're here, don't re-recompute the default computed values, just grab them
from the device.

At least until we support scrollbars properly, this size is going to be the
correct one. I've left a TODO to grab the proper one once we support it.
This allows to trivially test viewport units for now.

Fix#15513: Stop spacebar scrolling directly from the glutin window.
This completely removes spacebar scrolling using the current method, fixing #15513.
See #15513 for a discussion, as the _right thing to do_ is perhaps a UX problem - and perhaps worth a follow up.

No tests for these changes yet, as I'm just kicking off a discussion about how this should work.

geckolib: remove std::mem::transmute usages
We can make these look nicer with the FFIArcHelpers trait.

geckolib: use a global thread pool for styling
By having a single thread pool, rather than one per document, we use less memory. This addresses https://bugzilla.mozilla.org/show_bug.cgi?id=1324250.
This may be obvious to an experienced Rust programmer, but I went with raw pointers because trying to use `Option` global variables resulted in complaints about turning on feature flags in nightly Rust. Since this is for stylo, nightly features are not appropriate here.
