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.

So far the memory reporter aggregates reports from all processes, and
runs the system reporter only in the main process. Instead it is
desirable to have per-process reports. We do so by:
- creating a ProcessReports struct that holds includes the pid in
addition to the reports themselves.
- running the system memory reporter also in content processes.
- updating the about:memory page to create one report per process, and
add useful information like the pid and the urls loaded in a given
process.

Messages that are sent to the `Constellation` have pretty ambiguous
names.
This change does two renames:
- `ConstellationMsg` → `EmbedderToConstellationMessage`
- `ScriptMsg` → `ScriptToConstellationMessage`
This naming reflects that the `Constellation` stands in between the
embedding layer and the script layer and can receive messages from both.
Soon both of these message types will live in `constellation_traits`,
reflecting the idea that the `_traits` variant for a crate is
responsible for exposing the API for that crate.
Testing: No new tests are necessary here as this just renames two enums.

The `Constellation` previously held a `window_size` member, but this
assumes that all `WebView`s have the same size. This change removes that
assumption as well as making sure that all `WebView`s pass their size
and HiDIP scaling to the `Constellation` when they are created.
In addition
- `WindowSizeData` is renamed to `ViewportDetails`, as it was
holding more than just the size and it didn't necessarily correspond to
a "window." It's used for tracking viewport data, whether for an
`<iframe>` or the main `WebView` viewport.
- `ViewportDetails` is stored more consistently so that conceptually an
`<iframe>` can also have its own HiDPI scaling. This isn't something
we necessarily want, but it makes everything conceptually simpler.
The goal with this change is to work toward allowing per-`WebView` HiDPI
scaling and sizing. There are still some corresponding changes in the
compositor to make that happen, but they will in a subsequent change.
Testing: This is covered by existing tests. There should be no behavior
changes.

After #36320, `script` only depends on `webgpu` for its type aliases to
`wgpu_core` and `wgpu_types`. This change removes the dependency on
`webgpu` in favor of depending directly on the upstream crates. This
makes it so that you can change `webgpu` without recompiling `script`.
Testing: This change is covered by existing WebGPU tests and is mainly
just changing the way dependencies are accessed.

This breaks the `script_traits` dependency on `webgpu`. In general, the
`traits` crates shouldn't depend on Servo non-`traits` crates. This is
necessary to move "script to constellation" messages to the
`constellation_traits` crate, making it the entire API for talking to
the
constellation. This will break a circular dependency when that happens.
Testing: Successfully building is enough of a test for this one as
it is mainly moving types around.

This is the final step of #1799, where the majority of the generated
code for the JS bindings is now compiled as part of the script_bindings
build step. The remaining pieces in script must live there because they
refer to concrete DOM types; all code in script_bindings is generic over
the
[DomTypes](https://doc.servo.org/script/dom/bindings/codegen/DomTypes/trait.DomTypes.html)
trait.
My testing with incremental builds shows me a 12 second reduction in
build times on my 2024 M4 Macbook Pro when modifying code in the script
crate after these changes. Before this PR those changes took 20 seconds
to rebuild Servo, and now they take 8 seconds.
Testing: Existing WPT tests ensure no regressions.

Among other things this adds a new `EmbedderMsg::ShowSelectElementMenu`
to tell the embedder to display a select popup at the given location.
This is a draft because some small style adjustments need to be made:
* the select element should always have the width of the largest option
* the border should be part of the shadow tree
Apart from that, it's mostly ready for review.

`WindowMethods` is used by the embedding layer to get information from
the embedder. This change moves the functionality for getting screen
size and `WebView` offsets to `WebViewDelegate`.
This is important because `WebView`s might be on different screens or
have different offsets on the screen itself, so it makes sense for this
to be per-`WebView` and not global to the embedder. HiDPI and animation
state functionality will move to the embedder in subsequent changes.

- Remove `EmbedderMethods::get_user_agent_string`. This is now part of
the `Preferences` data structure, which should allow it to be
per-`WebView` in the future.
- Remove `EmbedderMethods::get_version_string`. This was used to include
some data along with WebRender captures about the Servo version. This
isn't really necessary and it was done to replace code in the past
that output the WebRender version, so also isn't what the original
code did. I think we can just remove this entirely.
The idea with these changes is that `EmbedderMethods` can be removed
in a followup and the rest of the methods can be added to
`ServoDelegate`. These two methods are ones that cannot be added to a
delegate as they are used during `Servo` initialization.
Testing: There is currently no testing for libservo. These changes are
meant
as preparation for adding a suite of `WebView` unit tests.

Note that `StyleRule` may not have the `CssRules` readily available,
they may need to be created. So the previous approach of providing
`CSSGroupingRule` with the `CssRules` is no good: it would require
writing them in advance, just in case they end up being used.
Therefore, this removes the `CSSGroupingRule::rules` field. Instead,
they are lazily obtained in `CSSGroupingRule::rulelist()` by downcasting
and calling the appropriate method for the subclass.
