This change adds a shadow-tree widget for `<input type=color>` elements.
It also involves some changes to the way layout interacts with the DOM,
because currently all `input` and `textarea` elements are rendered as
plain text and their descendants are ignored. This obviously doesn't
work for `<input type={color, date, range, etc}>`.

<details><summary>HTML used for the screenshot above</summary>
```html
<input type=color>
```
</details>
Testing: I doubt that this affects WPT tests, because the appearance and
behaviour of the widget is almost entirely unspecified.

This change adds a new `WebView` API `evaluate_javascript()`, which
allows embedders to
execute JavaScript code and wait for a reply asynchronously. Ongoing

tracked by a libservo `JavaScriptEvaluator` struct, which maps an id to
the callback passed
to the `evaluate_javascript()` method. The id is used to track the
script and its execution
through the other parts of Servo.

Rather than sharing the full image cache in a script_thread, the image
cache is now unique per document. This ensures that CSP factors no
longer affect whether the image is retrieved from the cache incorrectly.
To do so, the thread_pool is shared across all caches, but the store is
fresh. Except for the place_holder{image,url}, which are cloned. That's
because the `rippy_data` is only available in the constellation and no
longer accessible at the point that we need to create the document in
the script_thread.
Contrary to the description in #36505, the script_thread still has an
image_cache for this reason: so it has access to the store and
thread_pool to clone it.
With these changes, the two CSP tests no longer flake. Confirmed with
running the following commmand:

This is a followup to #36629, continuing to implement script-based
layout queries using the `Fragment`s attached to the `BoxTree`. In this
change, geometry queris (apart from parent offset) are calculated using
`Fragment`s hanging of the `BoxTree`.
In order to make this work, all `Fragment`s for inlines split by blocks,
need to be accessible in the `BoxTree`. This required some changes to
the way that box tree items were stored in DOM `BoxSlot`s. Now every
inline level item can have more than a single `BoxTree` item. These are
carefully collected by the `InlineFormattingContextBuilder` -- currently
a bit fragile, but with more documentation.
Testing: There are tests for these changes.

Previously, when processing animations, the compositor would sent a tick
message to each pipeline. This is an issue because now the
`ScriptThread` always processes rendering updates for all `Document`s in
order to ensure properly ordering. This change makes it so that tick
messages are sent for an entire WebView. This means that each
`ScriptThread` will always receive a single tick for every time that
animations are processed, no matter how many frames are animating. This
is the first step toward a refresh driver.
In addition, we discard the idea of ticking animation only for
animations and or only for request animation frame callbacks. The
`ScriptThread` can no longer make this distinction due to the
specification and the compositor shouldn't either.
This should not really change observable behavior, but should make Servo
more efficient when more than a single frame in a `ScriptThread` is
animting at once.
Testing: This is covered by existing WPT tests as it mainly just improve
animation efficiency in a particular case.

We previously ignored the opaque layout data field inside each node when
measuring a DOM node's memory usage. While some of the reachable memory
was accounted for by measuring the layout's box tree, measuring it via
the node ensures that we don't miss anything. Since there are often Arc
values involved, this means that the layout-thread box tree measurements
now look quite small, while reported JS heap usage has increased.
Testing: Manually compared about:memory for servo.org.

When doing any kind of query, up until now, containing block rectangles
were calculated by walking the `FragmentTree` until the node being
queried was found. In order to make possible answering queries without
walking the `FragmentTree`, `Fragment`s need to cache their cumulative
containing block rectangles.
This change adds a new `FragmentTree` pass (during construction) that
takes care of calculating and caching these values. The new cached value
is used during resolved style queries and also scrolling area queries
(with the idea that all queries will eventually use them).
In addition, extra `FragmentTree` walks used for cancelling animations
for elements no longer in the `FragmentTree` are integrated into this
new traversal.

There is a `WebView` in libservo (new) and a `WebView` in compositing

`WebView` from libservo. In addition there is also a trait exposed by
the compositor called `RendererWebView` which is a way for the
compositor to talk to libservo without a circular dependency.
This changes does some renames to make things clearer and so that there
is One Less WebView™:
- `compositing::WebView` -> `compositing::WebViewRenderer` (this is the

[ohos](9f93ccd942/ports/servoshell/egl/ohos/simpleservo.rs (L43))
), meaning that the baked in resources
are unused in servoshell.
For 3rd-party embedders, we probably also want to the let them know
early that they should initialize the resources, instead of
restricting the panics to production mode.
Rippy is the only resource which was required. Since it is only
253 bytes large, we just bake that resource in as a fallback.
We do want to make using the resources easy from tests, so we add
some logic to keep the baked in resources for tests only and initialize
the resource reader on first access.

libservo: Make zooming and HiDPI scaling work per-`WebView`
This change moves all zooming and HiDPI scaling to work per-`WebView` in
both libservo and Compositor. This means that you can pinch zoom one
`WebView` and it should now work independently of other `WebView`s.
This is accomplished by making each `WebView` in the WebRender scene
have its own scaling reference frame.
All WebViews are now expected to manage their HiDPI scaling factor and
this can be set independently of other WebViews. Perhaps in the future
this will become a Servo-wide setting.
This allows full removal of the `WindowMethods` trait from Servo.
Testing: There are not yet any tests for the WebView API, but I hope
to add those soon.

there were two kinds of messages that could be sent:
1. In-process messages from the `Constellation`
2. Cross-process messages from other parts of Servo
Now these two types of messages can be unified into one type. With that
done the compositor can simply keep a single `IpcReceiver` for all
messages, instead of having to set up a route for the cross-process
messsages. This decreases overhead of cross proceses messages a bit, but
more importantly solves an issue where Servo would rely on the
compositor's cross-process message route after the `Constellation` had
called `ROUTER.shutdown()`.

This PR introduces an initial, straightforward implementation for
displaying text selection and the caret.
This is achieved by passing the selection range and insertion point
index down to `TextFragment`, along with the starting offset of each
`TextFragment` to determine the proper range for displaying the caret
and text selection. Additionally, the `selected_style` was passed into
`TextFragment` to specify the background color.
During the final build phase, although whitespace is typically ignored
when constructing glyphs, we still need to retrieve it to render both
the caret and text selection at the correct location. This ensures that
whitespace is not overlooked when the `TextFragment` contains an
insertion point or selection range.
There are several improvements yet to be made, including:
- The caret is static and does not flash.
- The caret is not rendered when the input field is empty. (I suppose
there should be an easy fix somewhere but I haven't found it yet)
