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.

Moreover it makes `RangeBoundaryBase`'s interface cleaner, because it
already exposes the offset as a `uint32_t`.

The existing logic uses RightToLeft as a determinator of whether or not the start point is above-and-to-the-left of the end point. We can get that directly (and correctly) with IsInlineReversed.

There are two existing callers of IsTableCellFrame that both appear to want to
include BCTableCell frames, but don't. A patch in bug 1547759 will add a
third that wants the same.
The existing users of frame types all have to work around it being a distinct
type, and none appear to want the distinction. This removes that complexity.
If any callers want to make the distinction, they could implement QueryFrame
for BCTableCellFrame and use it. (It's not implemented now, though!)
In a little more detail, prior to this patch (in my debug build, at least):
* nsQueryFrame::ClassID::nsMathMLmtdFrame_id was 46
* nsQueryFrame::ClassID::nsTableCellFrame_id was 47
* nsQueryFrame::ClassID::nsBCTableCellFrame_id was 65
and entries 46 and 47 in sLayoutFrameTypes were
mozilla::LayoutFrameType::TableCell while entry 65 was
mozilla::LayoutFrameType::BCTableCell.
With this patch:
* nsQueryFrame::ClassID::nsBCTableCellFrame_id is 40
* nsQueryFrame::ClassID::nsMathMLmtdFrame_id is 41
* nsQueryFrame::ClassID::nsTableCellFrame_id is 42
and entries 40 through 42 in sLayoutFrameTypes are
mozilla::LayoutFrameType::TableCell.

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
are used in a lot of places but not related to `nsRange` directly. This
patch moves them into new static method only class, `mozilla::RangeUtils`.

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.

Per the discussion in:
https://groups.google.com/d/msg/mozilla.dev.platform/P79pwa9z5m8/iPYPAWPHCAAJ
They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.
