This passes the tests which are in https://github.com/web-platform-tests/wpt/pull/26472
Because of complications in #include handling, AbortFollower needs to be in a different
header file than AbortSignal, yet AbortSignalImpl needs to be available when AbortFollower is used.
Another option would have been to make DOMEventTargetHelper.h a bit different and uninline some hot methods
there or move them to another file, but that would have been equally bad and Abort* is used way less often.
AbortFollower and AbortSignalImpl are thus just moved to a new header.
Memory management is such that Listener in EventListenerManager owns the possible ListenerSignalFollower
instance which follows the relevant signal. In order to be able remove event listener,
ListenerSignalFollower has many similar fields as Listener.
ListenerSignalFollower can't easily have just a pointer to Listener* since Listener isn't stored as a pointer
in EventListenerManager.
ListenerSignalFollower is cycle collectable so that Listener->ListenerSignalFollower can be traversed/unlinked
and also strong pointers in ListenerSignalFollower itself can be traversed/unlinked.
There is an XXX in the .webidl, since nullability of signal is unclear in the spec pr.
Whether or not it ends up being nullable shouldn't change the actual C++ implementation.

This method can be and is used by derived classes as well as DOMEventTargetHelper
itself, so it does not need to be "Internal".

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.
The security checks outer window did here don't seem right, because the whole
point is that this method is only called by C++ code for its own purposes.
We're not adding random untrusted listeners via addSystemEventListener!

The CanCallerAccess check in the "webidl" version of
nsGlobalWindowOuter::AddEventListener was pointless, because bindings never
call things on outer windows.

Also switch the XPCOM-y version of EventTarget::AddEventListner to a
Nullable<bool> for aWantsUntrusted.
The three-arg overload of AddEventListener in ContentFrameMessageManager was
never called, so all the AddEventListener overloads there are not needed.

We can't have a null content in
ScrollbarActivity::StopListeningForScrollAreaEvents, because only viewport
frames have a null GetContent().

This is a large patch which tries to switch many of the external consumers of
nsGlobalWindow to instead use the new Inner or Outer variants.

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.

We don't have access to an appropriate context to create the dead wrapper in
when the callback is nuked, so instead, this patch creates a new dead wrapper
in the caller compartment each time the property is accessed. This is the same
behavior we'd get when trying to re-wrap a cross-compartment dead wrapper, so
it's consistent with the way we handle these situations elsewhere.
