This works modulo the existing nested layer order bug. Will be covered
by WPT /css/css-cascade/layer-import.html once the feature is enabled (I
can probably enable it right away for those tests, but I'd rather fix
the obvious bugs first).

Same, I want to land this separately to see if it affects
micro-benchmarks. If so, we might want to pack the layer order
_somewhere_ (though in this case I'm not sure where, tbh).
With this, layer rules should have an effect on the page. There are
a few things missing before being able to enable them:
* Fix nested layer order in some cases (when parent layers are declared
out of order, see the previous commit mentioning this).
* Some kind of OM representation, perhaps.
* Tests of course, which are coming in bug 1728722 and bug 1727276.
But this should be enough to allow playing with them.

I want to land this separately because we might want to get smarter with
the size of the Rule struct (maybe restricting layer order to a u8 per
scope and packing it with the source order, since 255 layers seem
plenty), but I'd rather do the obvious thing for now.

This code is really hot, and we've had perf regressions in the past for
introducing function calls in the hot path.
After the previous patch, add_rule is recursive and thus it can't be
inlined, causing a function call for each CSS rule.
This reduces the overhead by making the function take a rule list
instead, causing a function call per rule _list_, which should be
unnoticeable in practice.

For that, deal with children in add_rule recursively, to keep the
current layer name up-to-date in block layer rules.
This is not the final version of this code, as right now something like
this:
@layer A {
...
}
@layer B {
...
}
@layer A.A {
...
}
Would give A.A more priority over B, which is not correct. There are
tests for this incoming in wpt sync and such, but that can be tweaked
later.

This shouldn't have any behavior change, but is necessary because for
cascade layers we are going to need to handle the child rules / sheets
ourselves, in order to handle nested layers properly.

This should make attribute selectors roughly as fast as class selectors.
I think it's worth trying and see if perf bots complain on
micro-benchmarks and stylebench and such.
I made attributes more specific than local names, but less specific than
classes, which I think makes sense. When doing something like
foo[data-bar], filtering by data-bar seems likely to yield less elements
than filtering by foo.
While at it, remove the bloom filter pref since we shipped it in
bug 1704551 for 87 and we haven't heard complaints.

Not hooked anywhere yet, so this doesn't change behavior, but adds the
basic data model etc.
Adding parsing support requires some changes to cssparser to allow the
same at rule to be block and statement-like at the same time, so better
done separately.

Also, more directly go from StyleImageRendering to wr::ImageRendering.
* image-rendering: smooth the non-deprecated version of
OptimizeQuality, which maps to SamplingFilter::LINEAR /
wr::ImageRendering::Auto (which uses gl::LINEAR).
* image-rendering: pixelated maps to wr::ImageRendering::Pixelated /
SamplingFilter::POINT which is the same crisp-edges does.
Note that this uncovers that we were mapping image-rendering:
crisp-edges to wr::ImageRendering::Pixelated.
I'm going to preserve behavior on this patch but we should consider
switching that to map to wr::ImageRendering::CrispEdges on a
follow-up (filed bug 1728831 for this).

This is an oversight. I made selecteditem be -moz-html-cellhighlight,
but that's for inactive cells.
Use the inactive cell color everywhere (though android doesn't
differentiate). This matches other browsers and what was reviewed on
this bug.

break-before/after: page|column seem harder because you need to deal

We probably want to do this when they do something different, but for
now behavior should be the same and it causes some subtests to fail
because `getComputedStyle(..).fontFamily` for system fonts seems to
return -apple-system, but `.style.fontFamily = "-apple-system"` returns
`system-ui`.

This was being used when we had special code for gecko profiler in the servo
codebase but we just removed the last one. This is safe to remove now. The
"enabled" feature in the gecko-profiler crate is being controlled by
gkrust-shared directly now.

While the use of toml allows the flags to be separated, the split is
done via some shell shenanigans anyways, and servo's build.rs can
handle the same just fine.

Add initial support for the color-scheme CSS property, allowing pages to
choose between light and dark system colors per-element, and such.
Things that are left to do so that this can be enabled by default:
* Dark system colors on Windows / Android / Standins.
* Dark Canvas/CanvasText/Link visited colors (which right now are set
via PreferenceSheet).
* Dark form controls in nsNativeBasicTheme.
* Processing the color-scheme meta tag to fill-in
Document::mColorSchemeBits.
But this seems like enough progress to be landable on its own.

Alias -apple-system to it, and put it behind a pref for now. This is
pretty boring (read: uncontroversial hopefully) code. The follow-up work
is modifying StaticPresData to look up the fonts using system APIs,
probably. Maybe a bit more work if on macOS they can't be named.
