This is the first step toward moving the WebDriver implementation to
servoshell. This move will make it possible to start testing the
embedding API with WebDriver. See [this zulip thread][a] for more details.
While WebDriver will be able to use a lot of API commands to do what it
is doing now, there will still need to be some "cheat codes" for more
gnarly access to `ScriptThread` details. That's why we likely won't be
able to remove all WebDriver-specific messages from the API -- but maybe
they will be useful for embedders somehow.
A couple messages have to change as they depended on `script_traits`
types, particularly those that used `WindowSizeData` and `LoadData`. I
think this helps to encapsulate the WebDriver commands a bit more
though.

We were always treating an indefinite `stretch` as the automatic size.
This instead treats it as `0px` on min sizing properties, and as `none`
on max sizing properties, aligning with Blink and this recent CSSWG
resolution: https://github.com/w3c/csswg-drafts/issues/11006

Switch the delay to be used between the end of a previous run and the next, instead of the start
of consecutive runs. That ensure that we don't enqueue messages when processing is slower than
the delay.

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 is a step toward the renderer-per-WebView goal. It moves various
details out of `IOCompositor`.
- Image output: This is moved to servoshell as now applications can
access the image contents of a `WebView` via
`RenderingContext::read_to_image`. Most options for this are moved to
`ServoShellPreferences` apart from `wait_for_stable_image` as this
requires a specific kind of coordination in the `ScriptThread` that is
also very expensive. Instead, paint is now simply delayed until a
stable image is reached and `WebView::paint()` returns a boolean.
Maybe this can be revisited in the future.
- Shutdown: Shutdown is now managed by libservo itself. Shutdown state
is shared between the compositor and `Servo` instance. In the future,
this sharing might be unecessary.
- `CompositeTarget` has been removed entirely. This no longer needs to
be passed when creating a Servo instance.

This moves the GL accelerated media setup out of `RenderingContext`
which prevents making libservo dependo on the Wayland and X11 versions
of surfman explicitly. This support is experimental and (honestly) a bit
broken. I've confirmed that this works as well as it did before the
change.
The main thing here is that the configuration, which currently needs
surfman types, moves to servoshell. In addition:
1. Instead of passing the information to the Constellation, the setup is
stored statically. This is necessary to avoid introducing a
dependency on `media` in `webrender_traits`. It's quite likely that
`media` types should move to the internal embedding API to avoid
this. This is preserved for a followup change.
2. The whole system of wrapping the media channels in an abstract type
is removed. They could be either mpsc channels or IPC channels. This
was never going to work because mpsc channels cannot be serialized
and deserialized with serde. Instead this just uses IPC channels. We
also have other ways of doing this kind of abstraction in Servo so we
do not need another. The `mpsc` version was hard-coded to be
disabled.

When the embedder drops the last WebView handle, the webview is
destroyed, but the weak handle in libservo never gets cleaned up.
This patch adds a step to `spin_event_loop` that cleans up any weak
handles that have been destroyed. In theory, checking the strong count
should be more efficient than trying to upgrade each handle (only to
throw away the strong handle).

Make the rendering model of the `WebView` clearer:
1. `WebViewDelegate::notify_new_frame_ready()` indicates that the
WebView has become dirty and needs to be repainted.
2. `WebView::paint()` asks Servo to paint the contents of the `WebView`
into the `RenderingContext`.
3. `RenderingContext::present()` does a buffer swap if the
`RenderingContext` is actually double-buffered.
This is documented and all in-tree embedders are updated to work with
this new model.

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.
