::slotted() is already weird in the sense that it supports a pseudo-element
afterwards (so ::slotted(*)::before is valid for example).
::part() is weirder because you are supposed to allow stuff like
::part(foo):hover, ::part(foo):hover::before, etc.
In order to avoid making the already-complex parse_compound_selector more
complex, shuffle stuff so that we pass the progress of our current compound
selector around, and is the parsing code for each selector which decides whether
it's ok to parse at the given point.

Some of these were unused, some of them were only used in combination with
others, so I've unified them.
In particular, Forgetful and ClearAnimationOnlyDirtyDescendants were used only
together for a very specific task (the final animation traversal), so I merged
them into something that has that name.
ClearDirtyBits was unused, so I removed along with some code that would no
longer be called.

We don't have lossy currentcolor in the style system anymore, except for a
single property -moz-font-smoothing-background-color.
I could've converted it into a proper StyleColor and thread down all the
necessary information to the font metrics code.
But it doesn't really seem worth it given it's not exposed to the web, so I just
did the simplest thing, which is making currentcolor compute to transparent to
that specific property.
This patch also removes the stores_complex_colors_lossily code and related,
since now we always can cache computed colors.

This is the last step to be able to call matchMedia on display: none iframes.
This is green, except for some startup preference query tests that I'm going to
address in a blocking bug (making LangGroupFontPrefs global, basically).
The setup is similar to the ShadowRoot one, except we don't eagerly keep the
StyleSet around up-to-date, we only fill it if it ever had a pres context.

As discussed on IRC, fixed is only used for prefs right now, and:
* We already copy the fixed size to the monospace font.
* We already serialize the fixed family as "monospace" in the style system.
So it already works somewhat inconsistently. Making it an alias makes it
work consistently.

To be more similar between Rust and C++. This introduces GenericFontFamily and
exposes that plus FontFamilyNameSyntax to C++, using that where appropriate
instead of plain uint8_t as we were doing.
As a follow-up, as discussed on IRC with Jonathan, we can remove the -moz-fixed
family, and turn it just into an alias of Monospace.
The only non-trivial change is the MatchType changes, but they're ok I think.
The code already assumed at most one CSS generic, and the struct still takes 8
bits. I've verified that the relevant tests are passing (though try is closed).

This depends on https://github.com/eqrion/cbindgen/pull/308. Other than that,
this should be ready to go.
There's still a bit more magic than what I'd like to eventually. I should be
able to make cbindgen not rename types if it doesn't know about them, or
something.
But this removes most of the manual binding function implementations (all but
the ones that are declared via macros, which cbindgen doesn't see across).
I need to give up on the _Drop functions taking an Owned<T> because of
instantiation order fiasco. In order to define DefaultDelete I need Owned to be
complete, but I cannot do it after including the generated file since some
declarations already instantiate the specialization. Oh well.

UA style sheets only ever specify a single generic font family in font-family
properties, so we pre-create a unique, static SharedFontList for each generic
and change the representation of FontFamilyList to be able to refer to them
by their generic ID. This avoids having to share refcounted SharedFontList
objects across processes.

Each user agent style sheet has a unique URLExtraData object containing
its URL, but since they are refcounted objects, we can't share them
easily across processes. Rather than adding support for copying them
into a shared memory buffer like we will do with the Rust objects, here
we just set up a static array of URLExtraData objects per UA style
sheet. The array will be filled in in a later patch.
Rust UrlExtraData objects, once they are transformed into their
sharable form and copied into the shared memory buffer, will reference
them by an index.

Additonally, "shell" is unclear ("docshell" vs. "presshell"). Therefore, this

Similarly, some other method names of `Document` are also renamed from

They're only used in forms.css, and only for some anonymous content, which are
not content-accessible in the first place.
The only place where this could be exposed is calling
getComputedStyle(input, "::placeholder"), so I think this should be pretty safe,
but I've added a pref just in case.
While at it, also derive the Parse implementation. Less code is better.

structs as arguments, but declaring them in C++ as getting pointers.
This is another step in order to be able to autogenerate ServoBindings.h and

It'd be good to actually mark Owned and such as MOZ_MUST_USE_TYPE, so I sent
