The bitfield approach worked when the layer order was in pre-order, but
the spec was changed to make it work like post-order and I don't think
there's a way to keep it working like that, so keep the layer order in a
separate data structure that we look up when going from Rule to
ApplicableDeclarationBlock.
This is just a vector index operation so hopefully shouldn't be too bad.
This patch intentionally regresses @keyframe handling to some extent,
since we need a bit more complicated approach and it seemed worth
implementing in a separate patch.

We make it work on macOS by setting pointer-events: none + opacity: 0 rather
than visibility: hidden, and tweaking the caching setup to be Android-like.
Now that the scrollbars sheet is the same across platforms, move it to where
the rest of the UA sheets are. This way we guarantee that the RDM vs. Android
difference is less (just the ifdef at the top of the sheet).

The serialization of rotate should be updated to match the current spec.
1. If a rotation about the z axis (that is, in 2D) is specified, the property
must serialize as just an <angle>.
2. If any other rotation is specified, the property must serialize with an axis
specified. If the axis is parallel with the x or y axes, it must serialize
as the appropriate keyword.
Also, we need to handle the zero length vector separately because it is
parallel to every other vector but different from x axis, y axis, or z axis.

For that:
* Tweak the standin system colors to match the non-native theme.
* Use those system colors for button and field backgrounds.
* Rename the "should use system colors" bit to "is high contrast",
which is what it really is (specially now that we use system colors
also in non-high-contrast).
Border colors and other colors like the <input type=range> and such
might need some extra tweaking perhaps, but this is a decent start and
looks good in https://crisal.io/tmp/form-controls.html afaict (dark mode
toggle needs the color-scheme pref enabled of course).

This patch does three things:
* Unifies mac and gtk's buttonactivetext system colors (unships mac's from
content, but it was never meant to be exposed).
* Simplifies the forms.css rules, since <input type=color>'s color property
value doesn't affect its rendering in any meaningful way.
* Adds a buttonactiveface color, which we'll use to provide dark backgrounds
for buttons in Windows dark mode (and is good practice, since generally
every text system color should have a corresponding background).
So as-is it shouldn't change content-exposed behavior (except we stop exposing
the -moz-mac-buttonactivetext to content), but it's a worthy cleanup.

There's only one meaningful usage of it, which is to disable native
appearance of the <input type=range> (the windows native theme is no
longer exposed to content).
<input type=range> is inconsistent with every other native widget, which
only disables native appearance if the author specifies backgrounds or
borders. So make it match literally all other widgets and simplify a bit
the code.
We had no tests for this special behavior, let me know if you think it's
worth adding one (but I don't feel very strongly about it).

This patch adds the animation-timeline longhand property. For
shorthand, we will do that in the next patch.
This patch includes the aut-generated code in
devtools/shared/css/generated/properties-db.js, by `./mach devtools-css-db`.
Note:
1. we will use this property in Bug 1676791. For now, only make sure
we parse it and serialize it correctly.
2. The syntax of animation-timeline may be updated, based on the spec
issue: https://github.com/w3c/csswg-drafts/issues/6674.
However, it's not a big problem to update it later, so we still can
prototype this property based on the current version of spec.

I'm not aware of any reason we shouldn't do this, as it is interoperable
with other browsers, and it causes compat issues from sites that forget
to use the prefixed version.
Note this removes some #[parse(aliases)]. These only affect devtools
autocomplete behavior, and we avoid autocompleting -moz-prefixed
keywords when possible, so even though it's a slight behavior change,
it's worth it.

Note that the crash reason is sanitized so we're not exposing anything
sensitive.
I think my patch just changed the signature of the stack, as it didn't
change anything related to guards or what not. But without knowing why
is failing or a repro it's hard to know what's going on.
Printing the address at list would give us some indication of what might
be going wrong (perhaps we're using a static lock when we don't expect
one or such?).

We add scroll-timeline rule into the stylesheet rule type, and add a new
perference to protect it: layout.css.scroll-linked-animations.enabled.

This was needed before, since we used to optimize empty style rules away
(and thus we could get confused between the important and non-important
block for two different elements).
But now we always keep them, and thus there's no way for the same
declaration block to appear in two similar paths of the rule tree
without different cascade levels.
I found this because if we want to implement the revert-layer CSS-wide
keyword, we need to put the layer order in the rule tree. However the
same thing applies: The same style source will always have the same
layer for a given cascade-data rebuild, so I believe this should be
fine.

We need to compute the anonymous name on the fly while building the
CascadeData, otherwise we may see the same layer rule in two places due
to stylehseet sharing and make them incorrectly share a name.
