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 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.

These are no longer needed as we have the data we were looking for.

This commit adds a telemetry probe to determine the percentage of pages
that ever have a 'mousemove' event listener added to the DOM. This is for
determining how often APZ key scrolling could handle interleaved mousemove
events.
A flag is added to nsPIDOMWindow to track whether a qualifying event
listener was ever added to the DOM for this window, and is updated by
EventListenerManager. There are several other similar flags to this.
The probe is reported in nsGlobalWindow::FreeInnerObjects() so that it
can be compared exactly with the non-passive keyboard listener APZ probe.

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.
