This change is necessary to support the [CSS Highlight API](https://drafts.csswg.org/css-highlight-api-1/),
which uses `Selection` internally.
To replace `nsRange` with `AbstractRange`, some sections needed to be
adapted since `nsRange`-specific features were used.
Therefore, some methods (such as `GetRangeAt()`) may only be called if
the `Selection` is *not* of type `SelectionType::eHighlight`,
as it (per spec) returns an `nsRange`.
These methods will now `MOZ_ASSERT` if called for a highlight selection.
Additional methods are implemented which return `AbstractRange`
instead and are safe to be called for every selection type.
This commit also improves support of highlight features:
- Invalidation of highlight ranges: adding/removing Ranges in-place instead of
removing and re-adding the Selection object associated with the highlight.
- Ranges are only associated with the Selection that shares the same Document
- Fixed minor IDL issue

The Custom Highlight API allows a use case where a `Range` of a `Highlight`
is also used as `Selection`. Due to the decision to use the `Selection` mechanism
to display `Highlight`s, a `Range` can be part of several `Selection`s.
Since the `Range` has a pointer to its associated `Selection`
to notify about changes, this must be adapted to allow several `Selections`.
As a tradeoff of performance and memory usage, the `Selection`s are stored
as `mozilla::LinkedList`. A helper class `mozilla::SelectionListWrapper`
was implemented to allow `Selection`s to be in multiple of these lists
and without having to be derived from `LinkedListElement<T>`.
To simplify usage of the list, the use case "does this range belong to Selection x?"
is wrapped into the convenience method`IsInSelection(Selection&)`;
The method previously named like this was renamed to `IsInAnySelection()`
to be named more precisely.
Registering and unregistering of the closest common inclusive ancestor
of the `Range` is done when the first `Selection` is registered and
the last `Selection` is unregistered.

Added WebIDL interfaces as per spec, added some necessary changes to support maplike and setlike structures to be accessed from C++.
Added `::highlight(foo)` pseudo element to CSS engine.
Implemented Highlight as new kind of `Selection` using `HighlightType::eHighlight`. This implies Selections being added/removed during runtime (one `Selection` object per highlight identifier), therefore a dynamic container for highlight `Selection` objects was added to `nsFrameSelection`. Also, the painting code queries the highlight style for highlight Selections.
Implementation is currently hidden behind a pref `dom.customHighlightAPI.enabled`.

This change adds support for `content-visibilty: auto` as well as
showing and hiding content based on the relevancy of the content as
defined in the specification. Changes to relevancy are handled by
triggering updates in a set of `content-visibility: auto` frames stored
in PresShell at the appropriate time in the document lifecycle.
Some tests are now failing due to this feature exposing the failures,
but they will be fixed in later changes.
This change is a reland of an earlier version that properly updates
intrinsic sizes and triggers an update of remembered size for the
purposes of contain-intrinsic-size when content relevancy changes.

With this change, at least in `CharacterDataChanged` and `ContentRemoved`
causes hitting this assertion:
```
MOZ_ASSERT(aStartBoundary.Container()->IsInclusiveDescendantOf(aRootNode));
```
The reason is, they call it with `mRoot`, but the range has already been
disconnected from `mRoot`. The following patch fixes this.

This allows it to be forward-declared (while a nested class cannot be),
such that headers files that use RectCallback by pointer or reference
do not need to include nsLayoutUtils.h.
This avoids including nsLayoutUtils.h in nsRange.h.

We don't need these macros anymore, for two reasons:

2. clang now warns for the "temporary that should have been a declaration" case.

When we support `InputEvent.getTargetRanges()`, editor needs to create
`StaticRange` instances at starting to handle every edit operations/commands.
Therefore, we need a hack for saving allocation cost like `nsRange`.
This patch moves `nsRange::MaybeCacheToReuse()` and `nsRange::Shutdown()` to
`AbstractRange` to reduce copy&paste same code into `nsRange` and `StaticRange`.
However, `Create(nsINode*)` and `Release()` are duplicated unfortunately.

Previously, I added `Selection::mCachedRange` to save allocation cost of
`nsRange`. However, with the previous patch, we don't need the hack anymore
since ranges removed by `Selection::RemoveAllRanges()` are always kept in
the global cache of `nsRange`. Therefore, we can remove the ugly hack right
now.

It's difficult to consider the limit of cache since `nsRange` instance is

create too many instances.

`nsRange` instances are allocated a lot in the heap especially by editor and
spellchecker. The allocation cost is too bad for benchmarks. Therefore,
we should reuse released instances as far as possible. For managing it in
static factory methods of `nsRange`, we need to hide `nsRange` constructor.

This patch is based on Makoto Kato-san's patch.
This patch implements `mozilla::dom::StaticRange` class and creating some
static factory methods.
Then, makes `AbstractRange` has a utility method of `SetStartAndEnd()`
method of `nsRange` and `StaticRange` for sharing same logic in one place.
However, there are some additional work is required only in `nsRange`, e.g.,
`nsRange` needs to start observing mutation of the range, but `StaticRange`
does not it. Therefore, it's implemented as a template method which takes
`nsRange*` or `StaticRange*` as a parameter. Then, each `DoSetRange()`
method of them can do different things without virtual calls.
Note that `StaticRange` does not have any properties, methods nor constructor.
Therefore, we need additional API to test it.

For avoiding confusion between API of `nsRange` and `StaticRange`, I'd like to
rename `nsRange::CreateRange()` to `nsRange::Create()` because
`StaticRange::CreateStaticRange()` is too long name and
`StaticRange::CreateRange()` sounds odd. This patch renames it and changes
related methods to template methods to avoid runtime cost of temporary
`RawRangeBoundary` instance creation.
