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
box which owns the border that wins and becomes the collapsed border.

The specification doesn't say how to deal with percentages when
determining the minimum and maximum size of a table grid, so follow the
approach that Chromium uses.
Essentially, figure out the "missing" percentage from the non-percentage
columns and then use that to work backwards to fine the size of the
percentage ones.
This change is larger than one might expect, because this percentage
approach shouldn't happen for tables that are descendants of a flex,
grid or table container (except when there is an interceding absolute).
We have to pass this information down when building the box tree. This
will also make it easier to improve propagated text decorations in the
future.

If `width` is indefinite, treat the outer size as zero, instead of
treating the content size as zero and then adding padding and borders.
Also, we don't want a default minimum of zero to get added padding and
borders, and then defeat the point baove. So just ignore minimums and
maximums.
That seems to roughly match what other browsers do, but as usual, the
details are not interoperable, e.g. some browsers may obey min or max
sizing properties in some cases.

Instead of setting up a route for every image load in the DOM / Layout,
route all incoming image cache responses through the `ScriptThread`.
This avoids creating a set of file descriptor for every image that is
loaded.
This change requires having the `ImageCache` track the `PipelineId` of
the original the listener so that the `ScriptThread` can route it
properly to the correct `Window`.

This patch introduces a new handle-based webview API to libservo, with
two main design goals:
1. The lifetime of the handles controls the lifetime of the webview,
giving the embedder full control over exactly when webviews are
created and destroyed. This is consistent with how WebKitGTK’s
WebView works; the engine can only create webviews via a create
request, and can only destroy them via a close request.
2. All methods are infallible; if the constellation dies, the embedder
finds out when calling Servo::handle_events.
For the moment, the embedder is only responsible for creating the
WebView id, and not the internal TopLevelBrowsingContext data
structures. This is so that the ScriptThread is able to get a handle on
the new WebView's WindowProxy in the case that it's an auxiliary
browsing context. In the future, the embedder should also be responsible
for creating the TopLevelBrowsingContext and the ScriptThread should
have mechanism to associate the two views so that WebView creation is
always executed through the same code path in the embedding layer. For
now, it's enough that the embedder can get a handle to the new WebView
when it's creation is requested.
Once we replace EmbedderMsg with a webview delegate trait, we will pass
WebView handles to the embedder, rather than webview ids. We’ll also add
detailed docs, once the design settles.

Some of these tests were using `no_red_3x3_monospace_table-ref.xht` as
a reference. However, the reference has a single 3x3 table, while the
tests put each row on a different table. Thus text wasn't aligning well,
and the tests were failing on all browsers. Therefore this adds a new
reference for these tests.
Some other tests were instead adding a background on their columns.
These also get their own reference. But additionally, these tests
attempt to work as visual tests by overlapping two tables: one with
green text in front of another with red text. However, this feature
was broken since both tables had a background, so the underlying one
was not visible at all.
Therefore, I'm also removing the background of the table at the front.
Note that these tests come in pairs that just switch which one is in
front, so no functionality is lost.

Thanks to #34946 we don't have to recompute the min and max sizes, we
can get them from the `ContainingBlock`.
And then in `FlexContext` there is no need to store both the definite
and the min & max sizes of the container`, we can instead make do with
a single `FlexRelativeVec2<SizeConstraint>`.
This removes 1 of the 3 usages of `ContentBoxSizesAndPBMDeprecated`,
which is also good.

This test was failing on all browsers because before the paragraph
"Test passes if there is a filled green square and *no red*" was getting
styled with some unnecessary CSS which is not present in the reference.
Removing this CSS which is irrelevant to the actual table being tested
fixes the problem.

This used to be a struct that had a list of `CollapsedBorder`s, and the
maximum border width among that list.
However, this cached maximum border width was only used when resolving
the borders of the table. Therefore, for all grid lines except the first
and last ones per axis, this data was useless.
Also, in order to address #35123 I plan to retroactively zero out some
collapsed borders, which could invalidate this cache.
So this patch just removes the field and turns `CollapsedBorderLine`
into an alias of `Vec<CollapsedBorder>`.

Even though when painting the collapsed borders we were using the right
size, when sizing the table we were treating cells as having a border
of half the maximum border size along the entire grid line.
Now we only take the maximum among the borders adjacent to the cell.

This is causing a validation error because Github's static analysis sees
nightly.yml is calling bencher.yml but the latter requires permissions
that are more relaxed than the former (for android & ohos). Since other
workflows are not failing validation, they presumably already run with
default permissions that are satisfy bencher.yml's requirements
(bencher.yml is not relaxing the parent workflow's permissions as that
would defeat the usefulness of the validation that Github is enforcing).
In the long run we should move to default-restrictive permissions and
then have the top-level workflows declare the required permissions. The
permissions in bencher.yml seems to serve only as machine-checked
documentation, but as it is causing issues with nested calls that are
not possible at runtime, it seems like we have to either pass additional
permissions in top-level workflows (that are not needed, so that is bad)
or not declare them in nested workflows.
Fixes#35141.

We were just checking the computed `display` style, but a few HTML
elements can ignore some `display` values and generate a different
kind of box.
This uses the right check, though for now there is no difference in

The BlobState enum was used to track whether a GlobalScope
was managing any blobs (effectively like an `Option<HashMap>`,
being `None` if no blobs are being managed)
This is a pointless abstraction, as a HashMap is already allowed
to be empty. Removing `BlobState` and just using a
HashMap directly reduces noise and panic! invocations when
working with the blob store.
