Pretty much the same way we do for Shadow DOM.
There are a couple more places broken, but provided our fronted folks don't do
weird stuff nothing bad should happen, and the assertion that this allows me to
add should catch those if they do, so I'm punting on it for now.

The compartment-per-addon code was added so that we could segregate at least
some of the code from system-privileged add-ons into tagged compartments, even
when it ran in browser windows. That allowed us to apply certain special
behavior to them, such as enabling e10s shims, and to track some performance
characteristics.
The only remaining chrome-privileged add-ons now are system add-ons controlled
by us, and the shim system and per-compartment performance metrics are gone,
it no longer serves a purpose.

This is pretty much a straight-forward change except for a single thing, the
UpdateInsertionParent calls.
However, I cannot make any sense of them. They go through the inserted children
setting the insertion point, but then ClearInsertionPoints() is called.
ClearInsertionPoints calls XBLChildrenElement::ClearInsertedChildren, which sets
all the insertion points to null anyway.
Thus, I've removed that function completely.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

This also introduces JS::GetObjectRealmOrNull, which returns an object's realm,
or null if the object is a cross-compartment wrapper. In the new order,
wrappers can't have realms, since they must be shared across all realms in a
compartment. We're introducing this new function early (even though it's
*currently* possible to assign a realm to wrappers) in order to see in
advance if the possibility of returning null will cause problems.
(It looks like it won't.)

Doing it off a runnable makes the flattened tree inconsistent until that
runnable runs.
Also add an assert in frame construction that would've caught the first
only-unbind patch.

This is straightforward, with only two notable things.
- `#include "nsXPIDLString.h" is replaced with `#include "nsString.h"`
throughout, because all nsXPIDLString.h did was include nsString.h. The
exception is for files which already include nsString.h, in which case the
patch just removes the nsXPIDLString.h inclusion.
- The patch removes the |xpidl_string| gtest, but improves the |voided| test to
cover some of its ground, e.g. testing Adopt(nullptr).

I noticed that our current behavior in ContentRangeInserted is incorrect. Unlike
ContentInserted (where this code lived originally), ContentRangeInserted takes a
start and end element. I'm not sure if we ever take that path for new content that
needs style, but it seemed sketchy. And generally, it seems nice to just always
style new content the same way (though we still need to style NAC by the subtree
root, since it hasn't been attached to the parent yet).
For situations where there is indeed only one unstyled child, the traversal
overhead should be neglible, since we special-case the single-element in
parallel.rs to avoid calling into rayon.
Being more explicit about what we want here also makes us more robust against
the other handful of callpaths that can take us into
nsCSSFrameConstructor::{ContentRangeInserted,ContentAppended}. Currently we
can call StyleNewSubtree on an already-styled element via RecreateFramesForContent,
which triggers an assertion in the servo traversal.

Unfortunately couldn't add all the debug checks that I'd want, since we can't
assert that is not safe to run script in quite a few places :(

This includes, for example :hover.
Also removes the call to IsStyledByServo() in the document constructor, it's not
only unnecessary, but also we call UpdateStyleBackendType() too early.
