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.

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.

This patch makes `nsRange::Create()` reuse its instances automatically.
It's difficult to consider the limit of cache since `nsRange` instance is
created not so many in most cases, but only Find and Spellchecker sometimes
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.

Some `nsRange` static methods are useful in `StaticRange` and some of them

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.

This patch is based on the patch created by Makoto Kato-san.
`Range` and `StaticRange` have common base interface, `AbstractRange`.
https://dom.spec.whatwg.org/#abstractrange
This interface has simply returns `startContainer`, `endContainer`,
`startOffset`, `endOffset` and `collapsed`.
Different from the original patch's approach, this patch moves related
members in `nsRange` to `AbstractRange` since this approach avoids
virtual call cost. Additionally, this patch makes them not throw as
declared by the spec. As far as I know, the destruction cost of
`ErrorResult` may appear in profile so that we should avoid creating
the instance if we can avoid it.
Unfortunately, the instance size of `nsRange` becomes larger with this
patch. The size is changed from 176 to 184. I.e., now, `nsRange`
requires bigger chunk.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
AccessibleCaretEventHub is an nsISelectionListener of Selection whose type is
"normal". This is added only when nsFrameSelection::Init() is called and
accessible caret is enabled. Additionally, nsFrameSelection::Init() is
always called immediately after creating nsFrameSelection.
Therefore, when AccessibleCaretEventHub is installed to Selection, this is
always second selection listener and won't be installed multiple times. So,
Selection can store pointer of AccessibleCaretEventHub directly only when
it's enabled and the Selection needs to notify it of selection change.
This patch makes Selection stores AccessibleCaretEventHub with RefPtr, then,
makes Selection::NotifySelectionListeners() call its OnSelectionChange()
immediately after AutoCopyListener.
Unfortunately, this patch includes making of MOZ_CAN_RUN_SCRIPT_BOUNDARY and
MOZ_CAN_RUN_SCRIPT a lot since some methods of AccessibleCaretEventHub are
marked as MOZ_CAN_RUN_SCRIPT and including AccessibleCaretEventHub.h into
Selection.h causes compile the compile errors.

mozInlineSpellChecker::ReplaceWord() is used for replacing misspelled word
with a word. So, this is necessary to be distinguished from insertText
command when we implement InputEvent.inputType. So, we should make it
use TextEditor::ReplaceTextAsAction() instead (same as autocomplete).
This patch makes TextEditor::ReplaceTextAsAction() take optional argument
to make callers can specify replace range. Then, the range is a spellchecker
selection range if the caller is mozInlineSpellChecker::ReplaceWord().
Prior to this patch, it clones the range for normal selection, but it's
expensive and we may be able to reuse cached range of Selection in this case.
So, this patch makes Selection::AddRangeInternal() checks if given range is
in another Selection and use mCachedRange as far as possible.

Selection caches an nsRange instance for saving re-allocation cost and AddMutationObserver() and RemoveMutationObserver()'s cost when its RemoveAllRangesTemporarily() is called.
Then, the instance is detached from the Selection but still referring editing point. E.g., the only text node in TextEditor when its value is set. Therefore, it'll receive character data change notification and need to check whether the point is still valid with new text. However, the range will be always set new position later, i.e., immediately before going back to a part of Selection. Therefore, even if the point becomes invalid, nobody must not have any problems.
This patch makes Selection make the cached range not positioned, and makes nsRange ignore any mutations when it's not positioned.
