Previously, when the theme was set it was only set on currently active
`Window`s. This change makes setting the `Theme` stateful. Now the
`Constellation` tracks what theme is applied to a `WebView` and properly
passes that value to new `Pipeline`s when they are constructed. In
addition, the value is passed to layout when that is constructed as
well.
Testing: this change adds a unit test.

This change adds a new `WebView` API `evaluate_javascript()`, which
allows embedders to
execute JavaScript code and wait for a reply asynchronously. Ongoing
script execution is
tracked by a libservo `JavaScriptEvaluator` struct, which maps an id to
the callback passed
to the `evaluate_javascript()` method. The id is used to track the
script and its execution
through the other parts of Servo.
Testing: This changes includes `WebView` unit tests.

If a `WebView` is dropped immediately after creating it, the exit
pipeline message can arrive to the `ScriptThread` before the `Document`
is created for the pipeline. If this happens, we should still send a
message to the `Constellation` informing it that the pipeline is closed,
otherwise it will never know that this has happened properly.
Testing: This change includes a new unit test.
Fixes: #36807.

Expose a `ServoBuilder` for easily creating Servo instances using
default values. This change enables removing `EmbedderTraits`.
Testing: This is covered by `Servo` unit tests.

A `Servo` instance can only be constructed once per program execution
and cannot be passed between threads. This change adds a special thread
to run `Servo` unit tests. This will allow creating suites of `WebView`
unit tests.
Testing: This change includes a new test.

libservo: Make zooming and HiDPI scaling work per-`WebView`
This change moves all zooming and HiDPI scaling to work per-`WebView` in
both libservo and Compositor. This means that you can pinch zoom one
`WebView` and it should now work independently of other `WebView`s.
This is accomplished by making each `WebView` in the WebRender scene
have its own scaling reference frame.
All WebViews are now expected to manage their HiDPI scaling factor and
this can be set independently of other WebViews. Perhaps in the future
this will become a Servo-wide setting.
This allows full removal of the `WindowMethods` trait from Servo.
Testing: There are not yet any tests for the WebView API, but I hope
to add those soon.

libservo: Add a very simple `libservo` API test
This is the first step toward adding full testing for the `WebView` API.
The test added here simply starts up a Servo instance and verifies that
it does not crash when shutting down.
Testing: This change is a test, so there are tests for these changes.
