Servo has lots of `LayoutXYZHelper` traits that are used to define
additional methods on `LayoutDom<XYZ>`. We can replace them with `impl
LayoutDom<XYZ>` blocks, reducing the number of LoC and making it easier
to add or modify methods.
Testing: These should be covered by existing tests

A lot (and I mean, really a lot) depends on these constructors.
Therefore, this is the one spaghetti ball that I could extract and
convert all `can_gc` to `cx`. There are some new introductions of
`temp_cx` in the callbacks of the servo parser, but we already had some
in other callbacks.

This set of changes introduces a type matching the spec's "target
snapshot params" and uses it as part of determining the origin of new
documents. This has a side benefit of making our sandbox flag
determination more accurate, which leads to a bunch of sandboxing tests
passing as well as some new failures due to spec confusion about
origins.
Testing: Many new passing tests.

The commit contains several related changes:
* iframes that load javascript: URLs as part of the initial insertion
(ie. `<iframe src='javascript:...'>`) get a synchronous load event
dispatched
* javascript: URL evaluation that does not result in a string no longer
treated like a 204 response
* iframes that perform a javascript: URL navigation that does not result
in a new document no longer block the parent document load event
Testing: Lots of new tests passing.

We now check for this header and corresponding logic. The WPT tests
mostly pass, but rely on the `contentDocument` of the iframe to be
`null`. This is not something we did before, which means that iframes
were able to access the contents of error pages.
Instead, we now mark the document as internal with an opaque origin
according to the spec [1]. We shouldn't do this post-fact, but is
required since we first need to construct the document and enter its
realm, before we determine that it is an invalid document.

This change moves the `UserContentManager` abstraction from the
`ServoBuilder` to `WebViewBuilder` so that embedders can inject content
for each `WebView` independently. It also adds basic support for runtime
mutations to the `UserContentManager` API. Only adding new scripts is
currently supported, but future changes will add support for both other
mutations such as removal of scripts and addition & removal of
stylesheets. Future changes could also optimize the way mutations are
propagated to `ScriptThread`s by sending just the "delta" rather than
the whole `UserContents` structure for each mutation.
The `UserContentManager` now becomes just a convenient handle for the
embedders to invoke the mutation API while the actual management of the
manager's content is handled by the Constellation. The mutations are
relayed to the constellation via messages. The change also separates the
serialized version containg the user contents into a new `UserContent`
structure so that the API cannot be misused.
Testing: New unit tests have been added for the different scenarios
involving UserContentManager.

The specification has a dedicated method for destroying
documents. Parts of that method were scattered around
various parts of Servo machinery.
This patch consolidates these steps and follow the spec.
Additionally, it now correctly unloads iframes when
they are removed from a parent document.
As a result, the fetch-later WPT test now passes, as
it relies on the correct ordering of iframe unloading
to verify the fetch-later requests are sent.

Have more of the code follow the same path calling
`ScriptThread::spawn_pipeline`. Somewhat tricky was that the `origin` of
the new Pipeline was being determined in several different places, but
all in a consistent way for different types of page loads. This change
makes it is so that the origin is always determined in the same place.
This change is preparation for splitting out the creation of a new
`ScriptThread` and the spawning of its first pipeline.
Testing: This should not change observable behavior, so is covered by
existing tests.

The thing that this message does is to spawn a pipeline in a

already called `Pipeline::spawn`.

Servo has a lot of comments like this:
```rust
// https://example-spec.com/#do-the-thing
fn do_the_thing() {}
```
and I keep turning these into doc comments whenever I'm working close to
one of them. Doing so allows me to hover over a function call in an IDE
and open its specification without having to jump to the function
definition first. This change fixes all of these comments at once.
This was done using `find components -name '*.rs' -exec perl -i -0777
-pe 's|^([ \t]*)// (https?://.*)\n\1(fn )|\1/// <$2>\n\1$3|mg' {} +`.
Note that these comments should be doc comments even within trait `impl`
blocks, because rustdoc will use them as fallback documentation when the
method definition on the trait does not have documentation.
Testing: Comments only, no testing required

This implements LazyDOMString (from now on DOMString) as outlined in
https://github.com/servo/servo/issues/39479.
Constructing from a *mut JSString we keep the in a
RootedTraceableBox<Heap<*mut JSString>> and transform
the string into a rust string if necessary via the `make_rust_string`
method.
Methods used in script are implemented on this string. Currently we
transform the string at all times.
But in the future more efficient implementations are possible.
We implement the safety critical sections in a separate module
DOMStringInner which allows simple constructors, `make_rust_string` and
the `bytes` method.
This method returns the new type `EncodedBytes` which contains the
reference to the underlying string in either format.
Testing: WPT tests still seem to work, so this should test this
functionality.

The HTML specification defines the 'width' and 'height' attributes as
dimension attributes for the embedded content and images (img, iframe,
embed, object, video, source, input with image type)
https://html.spec.whatwg.org/multipage/#dimension-attributes and for the
tables (table, col, colgroup, thead, tbody, tfoot, tr, td, th) even
these attributes are marked as obsolete.
And UA are expected to use these 'width' and 'height' attributes as
style presentational hints for the rendering.
The embedded content and images:
https://html.spec.whatwg.org/multipage/#dimRendering
The tables:
https://html.spec.whatwg.org/multipage/#tables-2:the-table-element-4
Added missing 'width' and/or 'height' reflected IDL attributes:
- conformant 'unsigned long' IDL attributes for the 'img, source, video'
(with new macro 'make_dimension_uint*)
- obsolete 'DOMString' IDL attributes for the 'td, th, col, colgroup'
Moved the `fn attribute_affects_presentational_hints()` from Element to
specific HTML and SVG elements with attributes which affects
presentational hints for rendering.

This change makes it so that `<iframe>` sanboxing is equivalent to the
one used for Content Security Policy, which is how the specification is
written. In addition, these sandboxing flags are passed through to
`<iframe>` `Document`s via `LoadData` and stored as
`Document::creation_sandboxing_flag_set`. The flags are used to
calculate the final `Document::active_sandboxing_flag_set` when loading
a `Document`.
This change makes it so that `<iframe>`s actually behave in a sandboxed
way, the same way that `Document`s with CSP configurations do. For
instance, now scripts and popups are blocked by default in `<iframe>`s
with the
`sandbox` attribute.
Testing: This causes many WPT tests to start to pass or to move from
ERROR to TIMEOUT or failing later. Some tests start to fail:
-
`/html/semantics/embedded-content/the-canvas-element/canvas-descendants-focusability-005.html`:
This test uses a combination of `<iframe allow>` and Canvas fallback
content, which we do not support.
-
`/html/semantics/embedded-content/the-iframe-element/iframe_sandbox_navigate_other_frame_popup.sub.html`:
This test is now failing because the iframe is sanboxed but in the
ScriptThread now due to `allow-same-origin`. More implementation is
needed to add support for the "one permitted sandbox navigator concept."
