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.)

Add -moz-inert and -moz-script-level to the set of internal properties
that aren't included in "all".
-moz-inert may need to be uncacheable in the future if we make it not
change the pointer-events computed value. Left a comment to that effect.

-moz-inert CSS property reflects inert subtrees concept and can be used to implement HTML:dialog element and HTML:inert attribute

This avoids arbitrary precision loss when computing REM units and so on,
which is particularly important if we ever change the base of our app
units (but useful regardless).

This never worked, but it's more visible with the new form controls which have
more padding.
Make the anonymous div and co a pseudo-element, so that they inherit from the
<input> properly in all cases. This works for non-number inputs because the
editor root is a direct child of the <input>, but it doesn't for number inputs
because there's a flex wrapper in between.
This way overflow-clip-box: inherit does what we want. Reset the padding in the
inline direction, as the padding for <input type=number> applies to the arrow
boxes as well, and thus we'd double-apply it.

I think this should work for the animation throttling stuff.
Opacity works on the element tree, so I think this is sound.

This matches the new servo layout engine too, and thus removes some #[cfg]
gunk. Just use `flow` since it doesn't simplify the layout code as much.

I see atom dropping code generated in release builds for stuff like dropping the
"class" atom here:
https://searchfox.org/mozilla-central/rev/4df8821c1b824db5f40f381f48432f219d99ae36/servo/components/style/gecko/wrapper.rs#592
That is silly, and I hope making Atom be able to be used in const context will
help the compiler see that yeah, we're not doing anything interesting and the
atom shouldn't get dropped.
It also allows us to get rid of a few lazy_static!s, so we should do it anyway.
In order to accomplish this, compute the offset into gGkAtoms manually instead
of going through the static_atoms() array and then back to the byte offset.

D29542 fixed the bogus checks that was making nested pseudo-elements match
author rules. This adds tests and ends up being just a cleanup, though as it
turns out we it also fixes an issue with ::slotted() matched from
Element.matches.
