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.

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

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.
MozReview-Commit-ID: 91U22X2NydP
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 is for adding a pref that will allow web content to have key listeners
and use keyboard APZ, if they are marked passive. This commit also reworks
the function names and comments to make them more accurate.

This commit updates FocusTarget to collect whether there are key listeners
on the event target chain for the focused element. This is needed because we
cannot do async scrolling when this is the case.

This commit adds a telemetry probe to track the percentage of pages that ever
have a non-passive 'keydown' or 'keypress' event that could preventDefault()
APZ key scrolling of the root of a page.
A flag is added to each EventListenerManager to track whether it ever had
a qualifying event listener, and then in nsGlobalWindow::FreeInnerObjects()
the event targets that could preventDefault() a scroll are checked for this
flag. This check is done at nsGlobalWindow::FreeInnerObjects() so that the
DOM is still alive.
