The key here is that we only filter longhands if the shorthand is accessible to
content and vice-versa. This prevents the bug that prevented me to land this
patch before, which was us not expanding properly chrome-only shorthands.

The reason why bug 1355721 regressed this is because in non-e10s we definitely
flush before parsing the standards quirks-mode. And bug 1355721 introduced an
unconditional UpdateStylistIfNeeded, unless the counter style / font
equivalents.
That means that the stylist wouldn't remain on its initial state after the first
flush, which itself means that when the compat mode changed, the UA and user
rules were already on the stylist with the quirks mode keys. That makes
class-names be keyed in ascii lowercase.
After that no user style changed, so no rebuild happens for the cascade data in
the user origin, so we keep looking at the wrong keys indefinitely.
We should try to avoid the flush there and ensure that by the time we create a
pres shell the quirks mode is already up-to-date...

Right now Gecko uses a whole `Stylist` for stuff like XBL / Shadow DOM.
That's not great, because it has tons of unrelated logic, and also eats up a lot of memory. Also, it prevents us to optimize style changes in shadow hosts the same way we do for the document.
These patches mostly rejigger stuff around so that you can define a `DocumentStylesheetSet` and then an `AuthorStylesheetSet`, which would contain just the Shadow DOM sheets / XBL resource sheets.
It still doesn't introduce any use for the later, but that will come later.
There's a patch in this PR that requires Gecko changes, posted in https://bugzilla.mozilla.org/show_bug.cgi?id=1436798.

style: Cleanup StyleBuilder.
This is in preparation of a cascade optimization for custom properties.
This fixes various fishiness around our StyleBuilder stuff. In particular,
StyleBuilder::for_derived_style (renamed to for_animation) is only used to
compute specified values, and thus doesn't need to know about rules, visited
style, or other things like that.
The flag propagation that was done in StyleAdjuster is now done in StyleBuilder,
since we know beforehand which ones are always inherited, and it simplified the
callers and the StyleAdjuster code. It also fixed some fishiness wrt which flags
were propagated to anon boxes and text.

was a mess.

Otherwise removal of stylesheets may get out of sync with other DOM changes, and

This makes an element available in StyleAdjuster, and uses it to replace some of our CascadeFlags (the ones that don't represent restrictions on what's actually cascaded, actually).
That fixes handwaviness in the handling of those flags from style reparenting,
and code duplication to handle tricky stuff like :visited.
There are a number of other changes that are worth noticing:
* skip_root_and_item_based_display_fixup is renamed to skip_item_display_fixup:
TElement::is_root() already implies being the document element, which by
definition is not native anonymous and not a pseudo-element.
Thus, you never get fixed-up if your NAC or a pseudo, which is what the code
tried to avoid, so the only fixup with a point is the item one, which is
necessary.
* The pseudo-element probing code was refactored to return early a
Option::<CascadeInputs>::None, which is nicer than what it was doing.
* The visited_links_enabled check has moved to selector-matching time. The rest
of the checks aren't based on whether the element is a link, or are properly
guarded by parent_style.visited_style().is_some() or visited_rules.is_some().
Thus you can transitively infer that no element will end up with a :visited
style, not even from style reparenting.
Anyway, the underlying reason why I want the element in StyleAdjuster is because
we're going to implement an adjustment in there depending on the tag of the
element (converting display: contents to display: none depending on the tag), so
computing that information eagerly, including a hash lookup, wouldn't be nice.

All TElement's implement Copy, and are just pointers, so the double indirection
is stupid.

In practice the only NAC that possibly inherits from a grid or flex container
are pseudos.
In Gecko, if the root element is an item container, custom anon content would
also sometimes incorrectly inherit from that (see bug 1405635), but that's fixed
in Stylo.
We remove the IS_ROOT_ELEMENT blockification from the "skip display fixup"
check, since the root element is never NAC or anything like that, so there's no
need for the check.
This also fixes some reparenting fishiness related to pseudo-elements. We were
only skipping the fixup when reparenting anon boxes, not when reparenting normal
element styles, nor when reparenting other pseudo styles which are not anon
boxes.

The style adjuster knows about the pseudo, so there's no reason to thread that
info down.
There are more simplifications that can be done in followups, cleaning a bit the
cascade flags too, those will come later.
