This removes some complains that clippy will have in 1.95.
As this is mostly just match guards, it doesn't update MSRV.

anything.

Depends on #42251 for the overflow query.
Use containing block queries to implement the iteration of step [3.2.7.
Compute the Intersection of a Target Element and the
Root](https://w3c.github.io/IntersectionObserver/#compute-the-intersection)
within `IntersectionObserver` algorithm.
Contrary to the algorithm in the spec that maps the coordinate space of
the element for each iteration, we uses bounding client rect queries to
get the appropriate clip rect. And, to handle the mapping between
different coordinate spaces of iframes, we use a simple translation.
Due to the platform limitation, currently it would only handle the same
`ScriptThread` browsing context. Therefore innaccuracy any usage with
cross origin iframes is expected.
Testing: Existing and new WPTs.

In layout calculation within script, Instead of relying on the computed
values for overflow, query the overflow from layout for its used value
to accurately reflect whether an element establish a scroll container.
This query will be used for `IntersectionObserver` as well.
Testing: There are new `IntersectionObserver` WPT failures:
- `intersection-observer/isIntersecting-change-events.html`
- `intersection-observer/containing-block.html`
The failures are more than likely a false positive because intersection
observation steps wasn't supposed to trigger a reflow, but it was
before. It could be caused by the implementation of
`IntersectionObserver` in major UAs being a little bit different from
the spec in the calculation of `threshold` and `isIntersecting` .

Continuation of https://github.com/servo/servo/pull/42135, switch
Error::Type and Error::Range to also use CStrings internally, as they
are converted to CString for throwing JS exceptions (other get thrown as
DomException object, which uses rust string internally).
Changes in script crate are mechanical.

This change makes it so that the euclid types returned from layout
queries use the `CSSPixel` unit type when appropriate. The minimal set
of changes are also made to avoid having to convert these types to the
`UnknownUnit` in other places. There is still some casting that has to
happen to deal with the difference between Stylo's `CSSPixel` and
WebRender's `LayoutPixel`, but a followup changes will try to switch to
using one or the other.
Testing: This should not change behavior, so is covered by existing
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

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.

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.

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.
