These changes implement the restrictions for content rects required by
the ResizeObserver specification: inline boxes must return empty rects,
and any transforms must be ignored.
Testing: Newly passing tests.

Observers should trigger an observation when they are installed, but
this can only happen if a rendering update happens. This change makes
sure that a rendering opportunity is triggered. This isn't discused in
the specification because we only triggering rendering updates when
necessary for performance reasons.
Testing: This fixes a timeout in
`/intersection-observer/cross-origin-tall-iframe.sub.html`.
Fixes#39831.

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.

This updates all Rc that were ignored for malloc_size_of to use
conditional_malloc_size_of, unless the type in the Rc itself doesn't
support malloc_size.
Regular expressions used to search for all occurrences:
```
ignore_malloc_size_of = "Rc.*"
ignore_malloc_size_of = "Arc.*"
```
There are a couple left since they have nested Rc, which I don't know
how to fix.
To be able to define these, several new implementations were added to
`malloc_size_of/lib.rs` as well as
`HashMapTracedValues`.
Testing: if it compiles, it's safe

Adding an optional message to be attached to a SyntaxError. Unblocks
#39050.
The enum definition of Syntax is now `Syntax(Option<String>)`. Future
PRs should probably add more appropriate messages to some of the
`Syntax(None)`s.
Testing: Just a refactor
Fixes: Partially #39053

Parameterize and rename both `Layout::content_box_query` and
`Layout::content_boxes_query` to support the query of rendered padding
area and content area that accounts for transform and scroll. Both of
these query have been misleading for a time since they are using border
box, instead of content box of a Node.
This PR adds a new type `layout_api::BoxAreaType` to be passed from
`ScriptThread` to `LayoutThread` to query the respective area. It is
then used for the query within `IntersectionObserver` to pass several
WPTs.
Testing: Existing WPT Coverage.

Created wrapper for Stylo's IntersectionObserverMargin and cleaned up
repeated code.
Testing: Code compiles and `./mach test-unit tests/unit/style/` doesn't
have any errors. intersectionobserver.rs is able to utilize the struct.

IntersectionObserver needs to be able to query node geometry without
forcing a layout. A previous layout could have run without needing a
`StackingContextTree`. In that case the layout-less query should finish
building the `StackingContextTree` before doing the query. Add a new
type of layout API which requests that layout finishes building the
StackingContextTree.
This change also slightly simplifies and corrects the naming of
`Element` APIs around client box queries.
Testing: This should fix intermittent failures in WPT tests.
Fixes: #38380.
Fixes: #38390.
Closes: #38400.

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.
Fixes: This is part of #36232.

This is the first step toward implementing the IntersectionObserver
interface. It adds stubs which are exposed when a preference is turned
on. This is enough to get some sites with `IntersectionObserver` to
start working.
