The background color for the tree column headers is drawn using the
system APIs, but the foreground uses custom colors, which didn't follow
theme. This can lead to unreadable text with specific colors, e.g.
leading to black on black.
Fix this by using system colors for the foreground as well. It also
adds on-hover styling to match possible background change on hover.

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.

This implementation is more-or-less on par with the one from layout_2013
and in some cases better. There are still some cases where we don't
return the correct "resolved value," but this is enough to test
animations and transitions.
This patch computes the author-specified properties during the CSS cascade, and
removes the complex rule-tree-based implementation that tries to do the cascade
again.
This changes behavior in two ways, one of them which is not observable to
content, I believe:
* revert now re-enables the native styling. This was brought up in
https://github.com/w3c/csswg-drafts/issues/4777 and I think it is a bug-fix.
This is observable to content, and I'm adding a test for it.
* We don't look at inherited styles from our ancestors when `inherit` is
specified in a non-author stylesheet. This was introduced for bug 452969 but
we don't seem to inherit background anymore for file controls or such. It
seems back then file controls used to have a text-field.
I audited forms.css and ua.css and we don't explicitly inherit
padding / border / background-color into any nested form control.
We keep the distinction between border/background and padding, because the later
has some callers. I think we should try to align with Chromium in the long run
and remove the padding bit.
We need to give an appearance to the range-thumb and such so that we can assert
that we don't call HasAuthorSpecifiedRules on non-themed stuff. I used a new
internal value for that.

We have this optimization where, for non-generic structs, we generate just a
clone / move as the ToComputedValue / ToResolvedValue implementation.
This moves the optimization a bit further down, and refines it so that we still
generate all the relevant where clauses that make it sound, that is, that all
the ToComputedValue implementations of the fields return the same type.
Otherwise this wouldn't be sound and the type would need to become generic.
We add an escape hatch (no_field_bound) for fields that need to be cloned but
which don't implement the trait. This is right now only for the RefPtr<> in the
shared font-family list, and a piece of code in PaintWorklet which looks kinda
fishy, and probably should be fixed (but we don't ship it in Firefox and there's
a pre-existing FIXME for servo, so I punted on it for now).
The other thing this patch does is adding a bunch of ToComputedValue /
ToResolvedValue implementations that are trivial and were missing.

Expect forced-colors-mode-backplate tests to fail because they were passing for the wrong reason,
and the backplate is now properly applied, causing them to fail.
Remove tests for field and fieldtext from color-valid.html because they are tested again
in system-color-valid.html.

This should be less confusing. This is not supported outside of chrome:// or
user-agent stylesheets so we can name this however we want.

This also fixes some backwards logic in nsBlockFrame::ReflowDirtyLines, and adds
some static assertions to nsGenericHTMLElement that almost cause a very subtle
bug.

We never fast-reject numbers (because they could be part of a product). Without
this refactoring we'd accept stuff like calc(10) and crash during the evaluation
for obvious reasons.

This is the meat of the patch. There are a couple improvements done in a couple
later patches which should hopefully be straight-forward.

We'll use `CalcNode` as the specified value representation for <length> and
<length-percentage> values, so they'll have to implement ToCss.
There's one minor issue (two calls to to_css() instead of to_css_impl() which
are addressed later in the series).

I suggested the compat_mode bit in D62923 but it was somehow only applied to one
of the branches.
Also rustfmt the code for consistency, and add a local alias.

We don't actually share _that_ much code across them. This makes callers clearer
and code less confusing, IMHO.
This also has the benefit of not autocompleting path from devtools for
shape-outside.

Tweak the ShapeSourceRepresentation so that it doesn't store Option<>s.
Some renames so that GeometryBox doesn't conflict with the Gecko type, and some
other usual bits / re-exports to deal with cbindgen and generics.
Also, drive-by derive parsing of GeometryBox as it's trivial.
Doing this unfortunately is not possible without removing nsStyleImage first, so
let's do that before.
This makes us serialize in the shortest form for shape-outside, but that's what
we should do anyway.
(aside: the shapes code is a bit too generic, maybe we should unify
ClippingShape and FloatAreaShape...)
