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.

<applet> is not a thing anymore, and that selector in our UA sheet will never
match anyway, since an <applet> element will never have the BROKEN state.

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.

The '-moz-windows-accent-color-applies' media query matches when the Windows 10
accent color should be used as the background of the title bar.

Create an extra style context using the visited values (if they exist). This
mirrors the logic Gecko performs in nsStyleSet::GetContext for visited support.

While studying `GetContentStateForVisitedHandling` for adaptation to Stylo, I
noticed it calls through to `GetContentState`, which depends on external state
such as private browser, etc.
However, there's no need to call `GetContentState` here since this function
always clears both unvisited and visited if either is set.

This switches over layout's usage of PLArena to ArenaAllocator. This allows
us to build more files in unified sources and gets rid of various CONST masks.

The idea is to be able to call the right function during style resolution time
without doing a linear walk via nsCSSAnonBoxes::IsNonInheritingAnonBox.

I'm a bit concerned about the additional, probably un-inlineable, function call
in this path. I'm not sure how hot this path would be.
