modern syntax and thens hould not be gamut mapped/clipped in any way.

Such cas is invalidated out-of-band in `RestyleManager` because
their invalidation can be trivially determined. Don't consider them
again while determining the general-case relative selector invalidation.
Also fix `:only-child` being classified as a simple edge selector, and
prevent them from ending up in the any (`*`) bucket in `InvalidationMap`.

The only use of this type used to be carrying around an owning reference
to a thread-local. However, since bug 1577439 we're leaking the
allocation intentionally, so we can simplify the code to explicitly use
`Box::leak()`, which in turn removes all unsafe usage around these, and
allows us to drop the owning_ref dependency altogether.

This doesn't yet expose it to a11y but that will be done by the a11y
folks, since this blocks some of the a11y interop test-cases.
Modify the tests to not hit the network, and make -moz-alt-content not
exposed to content (we only need it for UA stylesheets).

This is the logical continuation of bug 1121792. This improves on the
existing support by totally removing all the manual nsTArray bindings,
which have always been a bit clumsy.
This is a prerequisite for bug 1281158 because I want to use ThinVec to
avoid a few extra heap allocations in the computed values of the Content
property.

Most of this code is already dead. The native appearance on macOS
doesn't work on dark mode, and on Windows and Linux we are already
overriding it.
Add a first-column tree property to be able to align the inner borders
on macOS properly.

We keep track of whether there was an origin color available so that we
can serialize hsl and hwb colors in modern srgb syntax.

Add one extra branch if we have before-change style but its display
is none, and the new style is not display:none. Also, we add an extra
subtest if we use the container query to change the display property.

Now we use the starting style if we have, to replace the before-change
style. This includes a minor refactoring of the handling of transitions
because it becomes a little bit complicated.
Differential Revision: https://phabricator.services.mozilla.com/D208571
Per spec, we define starting style for an element as the after-change style
with @starting-style rules applied in addition.
If an element does not have a before-change style for a given style change
event, the starting style is used instead of the before-change style to
compare with the after-change style to start transitions.
The basic idea in this patch is:
1. We add a flag to indicate if this element may have starting style. We
set this flag during its full matching, and store this flag in the
element data.
2. So during process animations, we check this flag, if this element may
have starting style and specifies transitions, we resolve the
starting style. Use it as the before-change style.
The implmentation in process_animations() and tests are in the following
patches.

The rules inside @starting-style doesn't apply to primary style, and
they are used only for CSS transitions (when computing starting style).
So adding a flag to make us easier to filter them out.

The values that we take from our parent should be zoomed in. Similarly,
root values should also be zoomed in by the effective zoom (for that, we
unzoom root values to zoom-independent pixels when storing them on the
device).
Container-relative units probably need more care / thought, because they
are in the layout (so zoom-independent) coordinate space already, since
they come from frames. Bug 1894104 is filed for this.

For the selector highlighter, we were retrieving the desugared selector of each
displayed rule, and using the selector text in querySelectorAll to retrieve the
elements matching the rule.
This can be very expensive, especially for deeply nested rule, for a feature that
might not even be used.
This patch is adding a method which takes a root node, and will return the
elements inside the root node that match the rule's selectors.
We're only exposing the method that existed in glue.rs to get the SelectorList
of a given Rule, and call `Servo_SelectorList_QueryAll` with it to get our NodeList.
A test file is added to ensure this works as expected.
