This should both be faster and simpler. Also will allow us in the future
to animate more pseudos without having to add a gazillion properties.
I think we should try to clear more stuff (maybe the whole animation
data) on unbind, but that's a bit tangential.

`nsTextFragment` is a storage of data node and DOM offset is `uint32_t`, but
some methods of `nsTextFragment` takes `int32_t` for the offset/length in
its text. Therefore, callers need to cast from `uint32_t` to `int32_t` if
the offset value is offset in a DOM node. Therefore, all methods of it should
take `uint32_t` values as offset/length in its text.

When XBL is disabled, no code in dom/xbl will be built. Also, adds ifdefs
to remove any of the XBL related code elsewhere. There's definitely more
that can be done here, but I think it's better to wait to do the rest of
the cleanup when we actually remove the code.

This penalizes a bit non-shadow-DOM content, in exchange of making Shadow DOM
slightly faster as well.
The biggest advantage of this is that all ContentRemoved notifications would see
the flattened tree before the changes, which is something a11y needs to be
correct.
XBL would still not be handled right by a11y, but that's not new and content
cannot do random stuff with XBL so it's not too bad.

We naively remove and then recreate accessibles when their content's
frame is reconstructed. By delaying the removal until we are certain the
content does not have a new layout frame, we can cut down on redundant
recreations.
When reconstructed content is re-inserted we can check it and its
subtree for missing frames and prune those accessibles from the tree.

This is intended to give a reasonable number that scales with the amount of
content in a website during page load, for scheduling purposes.
This effectively counts the amount of text connected to a document that isn't
likely to be inline style or script.
Potential improvements:
* Maybe have some more heuristics for hidden elements, like presence of the
`hidden` attribute?
* Maybe skip whitespace-only text? This does a pretty good job anyways because
whitespace nodes are usually pretty small (like a couple newlines and
spaces), so they don't add too much to the number. This could be done cheaply if
looking at sSpaceSharedString / sTabSharedString.
* Add some weight to some elements? Maybe images should have a fixed weight,
for example. Though you don't want 0x0 images and such to count... Maybe we
should add to this heuristic out of band when processing image loads or some
such.
* Handle shadow DOM and such better? Right now Shadow DOM and XBL are always
assumed visible as long as they're connected. You _can_ in theory do
something like stash a `<div>` inside a `<style>` element, attach a
ShadowRoot and such, and append a bunch of stuff inside. But I don't think
it's something we should be particularly worried about.
* Probably add some check to CharacterData::AppendText as well? Otherwise this
undercounts when loading big amount of text arrives via the network, for
example, but also I'm not sure we're optimizing for log files and such so it
might be ok.
In any case, this gives us a heuristic that we can iterate on later. This does a
pretty good job at representing the amount of content in the examples over here:
* https://faraday.basschouten.com/mozilla/executionorder/
For example for:
* https://faraday.basschouten.com/mozilla/executionorder/allinlinedual.html
You get an output like the following if you print the heuristic after each bind
operation (and de-duplicating them):
```
0
3 // Some whitespace in <head>
4 // Some whitespace in the <body>.
5
6
7
8
9
10
65547 // Actual content injected by the first script.
65548 // Some more whitespace.
131085 // Actual content injected by the second script.
131087 // Some more whitespace.
```

BindContext was going to have way more information at first, but then I realized
that most of the things I wanted to know were basically a flag away using the
parent node.
Still I think it's worth it, now experimenting with BindToTree will only mean
adding a field to a struct that's included from a couple cpp files, instead of a
massive pain.
I also think this is clearer, and doing this highlights quite a few
inconsistencies in our code which I've left untouched, but commented with
FIXMEs.
Steps are:
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsresult BindToTree(Document\* aDocument, nsIContent\* aParent,#nsresult BindToTree(BindContext\&, nsINode\& aParent)#g' $file; done
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's# nsIContent\* aBindingParent) override#override#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(Document\* aDocument, nsIContent\* aParent,#::BindToTree(BindContext\& aContext, nsINode\& aParent)#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsIContent\* aBindingParent)##g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(aDocument, aParent, aBindingParent)#::BindToTree(aContext, aParent)#g' $file; done
$ ./mach clang-format

We used to do that for FragmentOrElement too, but it was removed in D3533. The
explanation is a bit hidden in the revision, but quoting:
> Needed to remove the IN_SHADOW_TREE flag removal from unlinking since it may
> make a ShadowRoot claim not to be a ShadowRoot (nsINode::IsShadowRoot() would
> return false).
>
> In practice it was there because there was code that assumed that
> IsInShadowTree() -> GetContainingShadow() != nullptr
>
> But that stopped holding a while ago, and callers have been adjusted in the
> meantime to not assume that, so it should be fine to not remove the flag now.
We also unbind the Shadow tree on unlink now, which didn't use to happen.
This makes CharacterData consistent with FragmentOrElement.

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.
Various places in dom/ use the pattern:
already_AddRefed<NodeInfo> ni = ...;
which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason. To fix our static analysis code, we need to
eliminate instances of the above pattern.
Unfortunately, eliminating this pattern requires restructuring how Nodes
are created. Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`. We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.
While trying to repro bug 1484293 I noticed that this assertion failed:
https://searchfox.org/mozilla-central/rev/ef8b3886cb173d5534b954b6fb7eb2d94a9473d0/dom/base/ShadowRoot.cpp#160
(during unlink, while unbinding the kids)
We rely on GetComposedDoc returning the right thing during unbind to cleanup
some stuff (see bug 1473637 for example), so it should probably be correct all
the time, regardless of whether something is unlinked or not.
Also this makes GetComposedDoc() much faster, which is nice too, since we call
it somewhat often.
I removed NodeHasRelevantHoverRules, since it's unused (was used by the old
style system).
I moved the SetIsConnected(false) call for the shadow root to before unbinding
the kids for consistency with what Element does with the uncomposed doc flag,
now that the children's connectedness doesn't depend on the shadow root's.

Mostly automatic via sed. Only parts which I touched manually (apart from a
couple ones where I fixed indentation or which had mispelled arguments) are the
callers. I may have removed a couple redundant `virtual` keywords as well when
I started to do it manually, I can revert those if wanted.
Most of them are just removing the argument, but in Element.cpp I also added an
assertion for GetBindingParent when binding the ShadowRoot's kids (the binding
parent is set from the ShadowRoot constructor, and I don't think we bind a
shadow tree during unlink or what not which could cause a behavior difference).
