Refactored StyleComplexColor to support "complex" blending between
background (numeric) color and foreground color (currentColor).
Made explicit the distinction between numeric, currentColor and a
complex blend in Gecko and Stylo.
This is to support SMIL animation, for example, of the form:
<animate from="rgb(10,20,30)" by="currentColor" ... />

Atomic<bool> is implemented in terms of AtomicBase<uint32_t>, because that way
you don't need to depend on atomic 1-byte operations. That means that the rust
bindgen sees it as a u32, not a bool.
It's a bit concerning that the rust code seems to be doing an unsynchronized
read here, but given this is a RelaxedAtomic, that's probably ok.

It's only used for the error path in property parsing, so most of the time is
not useful.
Use the just-introduced NonCustomPropertyId::name to preserve the alias name,
which we were doing by passing the name around.

The six milliseconds spent in Olli's profile make me thing this is not getting
optimized and we expected.
Also move it to NonCustomPropertyId, so it works for aliases properly too.

And make transition-property more correct by serializing --0 unescaped instead

This would cause properties to change the value semantics between, e.g.,
@keyframes and non-@keyframes, which would be observable.
It happens not to be observable since the animation-* and transition-*
properties are not allowed in @keyframes, nor have bits in `contain`, and none
of the two properties are allowed in @page. But I think it's the right thing to
do.
This still causes a quirk like a property value in chrome / user origins being
potentially different if the value is specified via CSS var functions. But I
think that is fine.

We were working around the lack of alias support during parsing in
TransitionProperty by doing a Gecko lookup. That's a hack and is now gone.

This allows us to run the three.js examples without panicking, since they use self-drawing canvases to scroll the FPS graph.
