`TextRun`s use their parent style to render. Previously, these styles
were cloned and stored directly in the box tree `TextRun` and resulting
`TextFragment`s. This presents a problem for incremental layout.
Wrapping the style in another layer of shared ownership and mutability
will allow updating all `TextFragment`s during repaint-only incremental
layout by simply updating the box tree styles of the original text
parents.
This adds a new set of borrows when accessing text styles, but also
makes it so that during box tree block construction
`InlineFormattingContext`s are created lazily and now
`InlineFormattingContextBuilder::finish` consumes the builder, making
the API make a bit more sense. This should also improve performance of
box tree block construction slightly.
Testing: This should not change observable behavior and thus is covered
by existing WPT tests.

The two significant changes here are 1) a commit that frees memory used
to perform memory reporting once the reporting is complete, 2) memory
reporting for the system font service. There are various other commits
that remove `#[ignore_malloc_size_of]` attributes for data that we are
now able to measure, but they do not significantly change our
measurements when testing servo.org.
Testing: Comparing the output of about:memory on servo.org.

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.

Now that Stylo considers `servo` as the default feature, Servo doesn't
need to specify `features = ["servo"]`.
Also use the same crate names as Stylo, rather than renaming them with

Rework the `WebViewDelegate::intercept_web_resource_load` into
`WebViewDelegate::load_web_resource` and clean up internal messaging.
The main thing here is adding objects which manage the response to these
delegate methods. Now we have `WebResourceLoad` and
`InterceptedWebResourceLoad` which make it much harder to misuse the
API.
In addition, the internal messaging for this is cleaned up. Canceling
and finishing the load are unrelated to the HTTP body so they are no
longer subtypes of an HttpBodyData message. Processing of messages is
made a bit more efficient by collecting all body chunks in a vector and
only flattening the chunks at the end.
Finally, "interceptor" is a much more common spelling than "intercepter"
so I've gone ahead and made this change everywhere.

This patch implements the `FontFace` interface, but with some caveats
1. The interface is only exposed on `Window`. Support for Workers will
be handled in the future.
2. The concept of `css-connected` `FontFace` is not implemented, so
`@font-face` rules in stylesheets will not be represented in the DOM.
3. The constructor only supports using `url()` strings as source
and `ArrayBuffer` and `ArrayBufferView` are not supported yet.
A skeleton implementation of the `load` method of `FontFaceSet` is also
implemented in this patch. The intention is to support some web pages
that don't load without this method.

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`.

Before all timers were managed by the Constellation process, meaning
that they had to trigger IPC calls to be scheduled and fired. Currently,
timers are only used in the `ScriptThread`, so it makes sense that they
are per-process.
This change restores the timer thread functionality that existed before
avoided entirely. Completion is done using a callback that is sent to
the timer thread similarly to how fetch is done. This allows reusing the
existing task queue without making any new channels.
Fixes#15219.

These all happen now in *update the rendering*, typically after the
message that triggered this code is processed, though in two cases
reflow needs to be triggered explicitly. This makes `ReflowReason`
redundant though perhaps `ReflowCondition` can be expanded later to give
more insight into why the page is dirty.
- Handling of the "reflow timer" concept has been explained a bit more via
data structures and rustdoc comments.
- Theme changes are cleaned up a little to simplify what happens during
reflow and to avoid unecessary reflows when the theme doesn't change.
Notably, layout queries and scrolling still trigger normal reflows and
don't update the rendering. This needs more investigation as it's
unclear to me currently whether or not they should update the rendering
and simply delay event dispatch or only reflow.
In general, this is a simplfication of the code.
Fixes#31871.

Signed-off-by: Nico Burns <nico@nicoburns.com>
This is unfortuante, but it's the only way to stop making Stylo's
`malloc_size_of` depend on so many of Servo's dependencies. This is an
important step on the way toward releasing Stylo as standalone software.
When possible, we defer to the implementation of `MallocSizeOf` that is
in the base class.
One benefit of this change is that we start properly measure the size of
WebRender types, which before were always set to zero.
In addition the `Measurable` class is removed in favor of simply
manually implementing `MallocSizeOf`, which doesn't require
uncomfortably modifying the shape of data structures.

This is a step toward upgrading WebRender, which will be upgraded and
patched in the `third_party` directory. This change vendors the current
private branch of WebRender that we use and adds a `patches` directory
which tracks the changes on top of the upstream WebRender commit
described by third_party/webrender/patches/head.
The only remaining consumers are ::-moz-tree pseudo-elements (we used to
use ThinBoxedSlice for other data structures in the past).
Those are not particularly performance sensitive so I think just
double-boxing is fine. In the future, if we wanted to avoid the double
indirection, we could probably use the "thin" crate
(https://docs.rs/thin) or similar, which stores the length of the slice
along with the allocation, making the pointer thin in all
configurations, much like "ThinArc" does:
https://searchfox.org/mozilla-central/rev/1ce2eea39442190a71a1f8f650d098f286bf4a01/servo/components/servo_arc/lib.rs#891
In practice though, I don't think it's particularly worth it for this
specific case.

This will ultimately make it simpler to update crate dependencies and
reduce duplicate when specifying requirements. Generally, this change
does not touch dependencies that are only used by a single crate. We
could consider moving them to workspace dependencies in the future.
