This should help out quite a bit with uBO, which has lots of very
general attribute selectors. We invalidate per attribute name rather
than using a SelectorMap, which prevents matching for attribute
selectors that can't have changed.
The idea is that this should be generally cheaper, though there are
cases where this would be a slight pesimization. For example, if there's
an attribute selector like:
my-specific-element[my-attribute] { /* ... */ }
And you change `my-attribute` in an element that isn't a
`my-specific-element`, before that the SelectorMap would've prevented us
from selector-matching completely. Now we'd still run selector-matching
for that (though the matching would be pretty cheap).
However I think this should speed up things generally, let's see what
the perf tests think before landing this though.

This addresses a minor regression in bloom-matching.html. The common
case here is that there's no selector to the right of the
pseudo-element, so keep that path inline, while keeping all other checks
out of line.

In order to test its parsing and serialization, we expose it but protect
it behind a pref.
Besides, I would like to drop layout.css.aspect-ratio-number.enabled in
the next patch because the spec has been updated. It seems we don't have
to keep this pref and we should always use Number.

After bug 1632647, we can have pseudo-classes inside :not / :is /
:where, which the invalidation and matching code weren't handling.
Add a few tests for this stuff working as expected.

See https://bugzilla.mozilla.org/show_bug.cgi?id=932410#c2 for the
context for which this pseudo-element was added.
In the previous patch, I had to special-case range appearance because of
this pseudo-class, but that patch makes this pseudo-class completely
redundant, as now all form controls, themed and unthemed, display
outlines, unless the native theme displays a focus indicator on its own.
Remove the special case, and make ranges use outlines like everything
else rather than this bespoke pseudo-element.

The current API was pretty awkward as a result of two things:
* Not being able to create empty iterators for smallbitvec.
* We used to call the `F` function multiple times, but turns out that
collecting the declarations in a SmallVec was a perf win.
So clean this up so that it looks more similar to other APIs, taking an
iterator directly.
This is a bit more code, but hopefully easier to understand (and also hopefully
easier to optimize).
The motivation for this work is that I plan to investigate rebasing / landing
https://github.com/servo/servo/pull/20151, and I don't want more instantiations
of apply_declarations and such.

We still panic in a debug build, so that developers can notice when they
need to add a new static atom after modifying UA sheets.
We also add telemetry to note when this happens, add an app note to a
crash report, in case any crash later on occurs, and re-up the existing,
expired shared memory sheet telemetry probes so we can look at them
again.

When unhidding a ::marker element, we construct its generated item, and
then call StyleNewSubtree() on this generated item. During traversal, we
may update any animation related values in Gecko_UpdateAnimations(), which
may update the base styles for animation properties.
The test case is an animation segment from "null" to "inital" value. We
replace the "null" value with the base style value for the specific animation
property, so we can do interpolation properly.
(e.g. opacity: "null => initial" becomes "1.0 => initial")
If we don't update the animation related values in
Gecko_UpdateAnimations after generating ::marker, we may do
interpolation from "null" to "initial", which causes a panic.

That way elements inside links, form controls, etc have the right
contrast, even if the page overrides the color.
We can't do it when inheriting from transparent because we've already
forgotten about the "right" color to inherit, so the default color makes
sense. But that is a pretty unlikely edge case.
