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.

Instead, fix up the various content data structures when the stylesheet
is mutated. This makes reading a stylesheet not disable style sharing.

It's very hot when matching some kind of selectors like the ones in bug
1717267, and the two function calls show up in the profiles.

This changes font-family storage to reuse the rust types, removing a
bunch of code while at it. This allows us to, for example, use a single
static font family for -moz-bullet and clone it, rather than creating a
lot of expensive copies.

Specifically:
For "bullets", i.e. 'list-style-type:disc|circle|square|
disclosure-closed|disclosure-open', we use a built-in font
(-moz-bullet-font, which has glyphs for those symbols + space) to
retain mostly backwards compatible rendering for those. Authors may
override that with an explicit 'font-family' ::marker style though.
We also use this font for 'list-style-image' in case it would
fallback to one of the above when the image fails to load (so that
we get the same width space).
When the -moz-bullet-font is used we also set 'font-synthesis' to
avoid synthesizing italic/bold for this font. Authors may override
this with an explicit ::marker declaration.
We also set 'letter-spacing' and 'word-spacing' to the initial value
for bullets for web-compat reasons. Again, authors may override
this with an explicit ::marker declaration. (This breaks backwards-
compat slightly but makes us compatible with Chrome. We used to
ignore these for list-style-type:<string> too.)

Otherwise we assert due to the styles being different from the cached
ones, but it doesn't matter as these don't influence Gecko scrollbars.

This results in lots of new WPT test passes.
There were also a couple of WPT tests that turned out to be broken;
tab-size-inline-001 and -002 had errors in their reference files such
that they'd never pass anywhere. So those are fixed here.
Depends on D117331

So we update d property in the style system as well. This makes sure we
have the correct computed style and the correct rendering result.

Support fit-content for preferred size, min size, and max size. This
patch only implement the style system. For layout part, we will do that
in the following patches.
