Now the default of a color is the modern syntax and converting to legacy
syntax is very explicit.
AbsoluteColor::new can now take u8, f32 and Option<f32> as component
arguments and the flags will be set automagically.

I didn't find a single GTK theme that drew something useful for this:
* The container appearance isn't needed. It is a hack needed to get the
right styles for the native checkbox, but that's it, we don't need to
expose it to CSS.
* The label appearance was meant to draw the focus outline but since it
didn't work reliably we've been doing it manually since seven years
ago (see bug 582951 and bug 1312169).
Other platforms also don't use these so this simplifies the code a bit.
Depends on D185279

As a bonus we now can throttle some additive and visibility animations
more properly, because before we couldn't compute a change hint for
those but now we don't need to.

As per https://github.com/w3c/csswg-drafts/issues/8940.
I didn't do this in bug 1837638 because that's what the spec said at the
time, that's what other browsers did, and specially because if we did
this we had no way of runtime-disable nesting during development or if
things went south.
This means that we can't keep the nesting pref in 118, but that seems
fine (it's already enabled everywhere in 117).

Upcoming :has invalidation (Bug 1792501) requires 4 more flags, and we're out of space.
This change consumes the remaining 32-bit hole in `nsINode` to migrate selector-specific
node flags.
This has implications on 32-bit platforms, specifically on text nodes.

This patch introduces functional pseudo parameters, i.e. `::highlight(foo)`,
for `getComputedStyle()`. This required adapting the parse algorithm (`nsCSSPseudoElements::ParsePseudoElement()`) and forwarding the functional pseudo parameter into the style engine.

This commit removes the preference
mathml.legacy_maction_and_semantics_implementations.disabled
that controls whether we layout maction/semantics as an mrow +
extra style. It has been set to true since Firefox 106.

The idea is to share more memory when expanding nested rules (so being
able to share the whole :is() / :where() allocation), and same for the
Dependency computation (basically, share it across all descendant
selectors).
This prevents exponential explosion in cases like the one in bug 1844446
if you replace tag selectors by class selectors (so that we build
invalidation maps for them).

Everytime I look at this code I find more stuff to remove... :)
-moz-default-appearance: groupbox is not used anywhere.
menulist-text is, but it does nothing (it only would prevent drawing a
background, but we don't specify another background anyways).
