style: Use CascadeFlags for what they're for.
Now that we have an Element around on cascade, we can stop using the cascade
flags mechanism to pass various element-related state, like "is this element the
root", or "should it use the item-based display fixup".

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.

style: Make the TElement type arrive to the cascade function.
Not super-proud of this one, but it's the easiest way I could think of.

The changeset looks bigger than what it is, because while at it I've rewrapped a
fair amount of functions around to use proper block indentation.

Alternatives are parameterizing Stylist by <E>, which is not fun, or moving the
concrete element from layout_thread to layout, but that implies layout depending
on script, which isn't fun either.

Other alternative is implementing an empty enum and making anon boxes work on
it. It has the advantage of removing the annoying type parameter, but the
disadvantage of instantiating `cascade` twice, which isn't great, and having to
maintain all the boilerplate of a `TElement` implementation that just does
nothing.

layout: Stop overriding display of the ::-servo-details-content pseudo-element.
We only override it when there's no "open" attribute. But a display: none
pseudo-element is the same as no pseudo-element at all.

This should get the same behavior when iterating children in dom_wrapper.rs

style: Remove some unneeded indirection.
All TElement's implement Copy, and are just pointers, so the double indirection
is stupid.

I'm going to try to see if removing this double-indirection fixes some
selector-matching performance, and this is a trivial pre-requisite while I wait
for Talos results.

This allows us to have ensure_data() and clear_data() functions on the TElement

This also allows us to do some further cleanup, which I'd rather do in a
followup.

2b5c56e6a8 Move match and cascade temporaries to CurrentElementInfo
Before this change, the `ComputedStyle` struct that is part of permanent style
data per element holds 2 `StrongRuleNode`s (unvisited and visited) and 2
`Arc<ComputedValues>` (unvisited and visited).

Both rule nodes and the visited values don't actually need to be here.  This
patch moves these 3 to new temporary storage in `CascadeInputs` on
`CurrentElementInfo` during the match and cascade process.  Rule nodes are
pushed down inside the `ComputedValues` for later access after the cascade.
(Visited values were already available there.)

The permanent style data per element now has just the `Arc<ComputedValues>` for
itself and eager pseudo-elements (plus the `RestyleHint`).

layout: Stop mutating the style data from layout.
This is part of #16982.

Right now we have some code that tries to cache stuff in the style data during
layout.

This code is extremely rarely executed, only for `<details>` and `<summary>`.

I think if we really really want to cache these, we should find a place in the
layout data for it.

For now, let's move it away (and all the other layout code) from mutating the
style data from layout.

8375319928 Auto merge of #16876 - asajeffrey:constellation-rename-frames, r=cbrewster
Renamed constellation::Frame to constellation::BrowsingContext

<!-- Please describe your changes on the following line: -->

Now that script has `WindowProxy` rather than `BrowsingContext` objects, we can rename `Frame` in the constellation to `BrowsingContext`. In particular, this means that `FrameId`s are now `BrowsingContextid`s, which better captures their purpose (and they are used in a lot of places, not just the constellation).

Just use WebRender's ClipId directly. This will allow us to create and

make it easier to have Servo responsible for creating the root
scrolling area, which will allow removing some old hacks in the future.
