This patch exposes a servo internal DOM API that is only made available to about:
pages on the navigator object to request memory reports. The about:memory page itself is
loaded like other html resources (eg. bad cert, net error) and makes use of this new API.
On the implementation side, notable changes:
- components/script/routed_promise.rs abstracts the setup used to fulfill a promise when the
work needs to be routed through the constellation. The goal is to migrate other similar
promise APIs in followup (eg. dom/webgpu/gpu.rs, bluetooth.rs).
- a new message is added to request a report from the memory reporter, and the memory reporter
creates a json representation of the set of memory reports.
- the post-processing of memory reports is done in Javascript in the about-memory.html page,
providing the same results as the current Rust code that outputs to stdout. We can decide
later if we want to remove the current output.

This is the first step toward removing `WindowMethods`, which will
gradually be integrated into the `WebView` and `WebViewDelegate`. Sizing
of the `WebView` is now handled by the a size associated with a
`RenderingContext`. `WebView`s will eventually just paint the entire
size of their `RenderingContext`. Notes:
- This is transitionary step so now there is a `WebView::resize` and a
`WebView::move_resize`. The first is the future which will resize the
`WebView` and its associated `RenderingContext`. The second is a
function that the virtual `WebView`s that will soon be replaced by a
the one-`WebView` per `WebView` model.
- We do not need to call `WebView::move_resize` at as much any longer
because the default size of the `WebView` is to take up the whole
`RenderingContext`.
- `SurfmanRenderingContext` is no longer exposed in the API, as a
surfman context doesn't naturally have a size unless a surface is
bound to it.

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.

Expose two easy-to-use wrappers around `SurfmanRenderingContext` that
make the API simpler to use:
- `WindowRenderingContext`: This `RenderingContext` is a newtype around
`SurfmanRenderingContext` takes a `raw-window-handle` display and window
and creates a full window rendering context.
- `SoftwareRenderingContext`: is wraps `SurfmanRenderingContext` and
adds a swap chain in order to expose a software GL rendering context.

Using environment variables is not really an option on ohos/android,
so add a CLI option to configure tracing.
Making it a `pref`, so that we can persist the filter
might also be desirable.

- Run `cargo fmt` on `webxr` and `webxr-api`
- Fix clippy warnings in the existing `webxr` code
- Integrate the new crates into the workspace
- Expose `webxr` via the libservo API rather than requiring embedders to
depend on it explicitly.

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`).

Flatten and simplify Servo's preferences code. In addition, have both
preferences and options passed in as arguments to `Servo::new()` and
make sure not to use the globally set preferences in `servoshell` (as
much as possible now).
Instead of a complex procedural macro to generate preferences, just
expose a very simple derive macro that adds string based getters and
setters.
- All command-line parsing is moved to servoshell.
- There is no longer the concept of a missing preference.
- Preferences no longer have to be part of the resources bundle because
they now have reasonable default values.
- servoshell specific preferences are no longer part of the preferences
exposed by the Servo API.

- The default value for SwapInterval is 1,
so setting it to 1 changes nothing
- We don't clear the screen immediately anymore, which was the only
useage of the egl bindings
this saves us from duplicated EGL bindings.

Bundle resource files into the .hap, so they are available

This should slightly reduce the binary size in debug and
