This change adds the second major part of the new API: delegates which
have methods called by the Servo loop. When a delegate is set on a
`WebView` or on `Servo` itself, the event loop will call into
appropriate delegate methods. Applications can implement the delegate on
their own structs to add special behavior per-`WebView` or for all
`WebView`s.
In addition, each delegate has a default implementation, which
automatically exposes "reasonable" behavior such as by-default allowing
navigation.
There's a lot more work to do here, such as refining the delegate
methods so that they all have nice interfaces, particulary with regard
to delegate methods that need an asynchronous response. This will be
handed gradually as we keep working on the API.

A box is usually sized by the formatting context in which it participates.
However, tables have some special sizing behaviors that we implemented
with a `content_inline_size_for_table` override.
However, breaking the assumptions of the formatting context isn't great.
It was also bad for performance that we could try to layout a table
among floats even though it wouldn't en up fitting because of a larger
min-content size.
Therefore, this changes the logic so that formatting contexts use some
special sizing for tables, and then tables only override that amount
when there are collapsed columns. Eventually, we should try to remove
that case too, see https://github.com/w3c/csswg-drafts/issues/11408

Remove this event which is completely unused. In addition, lots of code
becomes dead once this happens, so remove that as well. It may be
possible that a different behavior is necessary immediately following a
window resize, but the new API will handle this in a different way than
this embedder event -- which complicates how the event loop is spun in
both the API and servoshell.

These will be a single method in the upcoming `WebView` delegate, so it
makes sense to also combine the internal message to match this. In
addition, since `LoadStatus` is now exposed to the API if there is ever
the need to add more statuses or to move to an event-based version, the
API is already set up for this.

The outer display type of a table element applies to the table wrapper
box. The table grid box needs to be block-level as defined in
https://drafts.csswg.org/css-tables/#table-grid-box
Therefore this sets `display: table` on table grid boxes, and then when
painting collapsed table borders we can use the usual logic to compute
the StackingContextSection.

In #35075 I painted them in front of the decorations (backgrounds and
borders) of any block-level box in the same stacking context. I did that
because other browsers paint them in front of the decorations of the
descendants of the table, but my approach also painted them in front of
decorations of following siblings of the table, which was wrong.
This patch makes it so that collapsed table orders are painted in the
same step as decorations. However, tables defer painting their collapsed
borders after the decorations of their descendants.
This matches Blink and WebKit, and brings us closer to Gecko (which is
slightly different in some corner cases).

`EmbedderMsg` was previously paired with an implicit
`Option<WebViewId>`, even though almost all variants were either always
`Some` or always `None`, depending on whether there was a `WebView
involved.
This patch adds the `WebViewId` to as many `EmbedderMsg` variants as
possible, so we can call their associated `WebView` delegate methods
without needing to check and unwrap the `Option`. In many cases, this
required more changes to plumb through the `WebViewId`.
Notably, all `Request`s now explicitly need a `WebView` or not, in order
to ensure that it is passed when appropriate.

When we try to place a table next to some floats, and it doesn't fit
vertically, then we try again considering more floats. And as an
optimization we were using the previous width of the table as a minimum.
However, this was wrong, because the table might accept a smaller width
when the available space is smaller than beforehand.

There is some interesting history to this change:
* https://github.com/servo/servo/issues/33495: Servo crashes on
Cloudflare's turnstile, because we didn't compute style for
elements inside shadow trees
* https://github.com/servo/servo/pull/34298: Resolves the issue
by computing style for children of a potential shadow root,
in addition to the children of an element
* https://github.com/servo/servo/pull/34701: Changes layout
of elements with shadow roots such that only the contents
of the shadow root are laid out
Now, we compute style for both the children of the element
and a potential shadow root, but only lay out the contents
of the shadow tree (if there is one).
This behaviour is not technically incorrect,
since regular children are not included in layout
their style doesn't matter. However, it is
inefficient: the only case where we need to compute
style for a child of a shadow host is when
that child is an assigned slottable in a slot
somewhere else.
This part 1/n of upstreaming the changes necessary
to lay out `<slot>` contents. Note that trying to compute
style for `<slot>` contents *and* children of shadow hosts
will crash in stylo, since it expects to see each
element only once.

Many types used directly in the `libservo` API are in the
`script_traits` crate, which was created to break circular dependencies.
Move all API exposed types to `embedder_traits` which now contains types
exposed via the `libservo` embedding API. Also expose these at the root
of the `libservo` `servo` crate so that the API won't break when they
move around in the future.
The idea with `embedder_traits` in the future is that it contains types
that are available throughout servo because they are used in the
embedding API and thus should have minimal dependencies on other Servo
crates (a bit like `base`).

We were painting collapsed borders without taking into account that some
tracks might have been "removed" by `visibility: collapse`.
This just sets the sizes of these tracks to zero. Note this implies that
collapsed borders may overlap each other, or overlap cell contents, but
this seems to match Blink.

If a collapsed border has the `currentcolor` color, we were resolving it
using the color of the table. Now we resolve it using the color of the
