This change makes it so that every `GlobalScope` can contain an optional
`FontContext`. This will be necessary for every `GlobalScope` that
accesses canvas. Currently, `FontContext` is created and accessed via
the canvas worker thread, but this means that web fonts are not
available to canvas. This change will eventually make it possible for
canvas to share web fonts with the `Document` that owns them.
Testing: This should not change behavior and is thus covered by existing
tests.

Building on the preference observer work from #38649, we now
automatically install an observer when multiprocess mode is enabled.
This observer notifies the constellation of updated preferences, which
in turn notifies each content process so the changes will be reflected
into script/layout as expected. There's a unit test that verifies this
works correctly by checking a preference-gated WebIDL property before
and after the preference is toggled.
Testing: New unit test added.
Fixes: #35966
Depends on #38649.

Instead of using WebRender hit testing to update the cursor, base it on
layout hit tests. This allows removing the majority of WebRender hit
test items and finally opens up the possibility of adding support for
custom cursors. In addition, this change fixes an issue where cursors
were not set properly on areas of the viewport that extended past the
page content.
Testing: This is difficult to test as verifying that the cursor changed
properly is beyond the capabilities of Servo's test harnesses.

1. The `shared` directory is for the "_traits" crates, which will likely
be moved out of this directly at some point and renamed "_api". These
crates expose the API of crates to avoid circular dependencies.
`Snapshot` isn't really this.
2. `Snapshot` is essentially a specialied kind of `Image` so it makes
sense that it is grouped with other image-related things in `pixels`.
Testing: This should not change any behavior so is covered by existing
tests.

Replace the holder of actual pixel data of the ImageBitmap interface
([[BitmapData]] slot) from Vec<u8> to snapshot::Snapshot (image bitmap
with metadata).
https://html.spec.whatwg.org/multipage/#the-imagebitmap-interface
It will allow to have all required information (e.g. size, pixel format,
alpha mode)
for further drawing processing to/from canvas2D output bitmap.
Testing: No required tests

Removed unused dependencies in various crates using cargo-machete, grep
and cargo-udeps.
Testing: The CI tests if any dependencies were used that are removed.

This is the last big change necessary to create the
`constellation_traits` crate. This moves the data structure for messages
that originate from the `ScriptThread` and are sent to the
`Contellation` to `constellation_traits`, effectively splitting
`script_traits` in half. Before, `script_traits` was responsible for
exposing the API of both the `ScriptThread` and the `Constellation` to
the rest of Servo.
- Data structures that are used by `ScriptToConstellationMsg` are moved
to `constellation_traits`. The dependency graph looks a bit like this:
`script_layout_interface` depends on `script_traits` depends on
`constellation_traits` depends on `embedder_traits`.
- Data structures that are used in the embedding layer
(`UntrustedNodeAddress`, `CompositorHitTestResult`, `TouchEventResult`
and `AnimationState`) are moved to embedder_traits, to avoid a
dependency cycle between `webrender_traits` and
`constellation_traits`.
- Types dealing with MessagePorts and serialization are moved to
`constellation_traits::message_port`.
Testing: This is covered by existing tests as it just moves types
around.

This change creates a `constellation_traits` crate. Previously messages
to the `Constellation` were in the `compositing_traits` crate, which
came about organically. This change moves these to a new crate which
also contains data types that are used in both compositing/libservo and
script (ie types that cross the process boundary). The idea is similar
to `embedding_traits`, but this is meant for types not exposed to the
API.
This change allows deduplicating `UntrustedNodeAddress`, which
previously had two versions to avoid circular dependencies.
