This patch adds simple stubs to convert between the nsISimpleEnumerator
iteration protocol and the JS iteration protocol.
Each iterable object is required to have an @@iterator method which returns an
object implementing the iterator protocol. The later objects, by convention,
also have such a method which returns the object itself.
This patch adds both a @@iterator() and entries() methods to
nsISimpleEnumerator. The former returns an iterator which returns plain
nsISupports objects. The latter accepts an IID and queries each element to
that IID before returning it. If any element fails to query, the error is
propagated to the caller.

Loading SpecialPowers into frame scripts has side-effects, detailed in part 1,
which are undesirable. The main side-effect that I'm trying to get rid of here
is the force-enabling of permissive COWs in frame script scopes, which is
blocking changes that I need to make elsewhere. But both that and the scope
pollution it causes are likely to allow code to work when running in
automation which fails in real world usage.
This patch changes our special powers frame scripts to load specialpowers.js
and specialpowersAPI.js as JSMs, which run in their own global, but define
most of the same properties on our frame script globals.
Most other callers still load those scripts via <script> tags or the subscript
loader, and should ideally migrated in a follow-up. But even so, this patch
still gives us a cleaner separation of the frame script and non-frame-script
loading code.

I generally tried to preserve the behavior of consumers where they treated an
exception from getInterface(Ci.nsIContentFrameMessageManager) as a signal to use
some sort of fallback.
I did change the behavior of consumers that walked up to the root same-type
docshell before getting the message manager to just get it directly from the
docshell they have. Please review those parts carefully, and let me know if you
want me to ask some subject area experts to review those.

DocShells are associated with outer DOM Windows, rather than Documents, so
having the getter on the document is a bit odd to begin with. But it's also
considerably less convenient, since most of the times when we want a docShell
from JS, we're dealing most directly with a window, and have to detour through
the document to get it.

This is a quick-and-dirty port. It might be nice to replace
SpecialPowersObserver with the webextensions content script injection
system at some point, but that isn't practical right now (since WE experiments
cannot implement new APIs visible to content scripts).

If result is zero, getPrivilegedProps() would incorrectly return null.

This also removes any redundant Ci.nsISupports elements in the interface
lists.
This was done using the following script:

nsFrameLoader is on WebIDL bindings, so those QIs are no-ops anyway, unless the given object is no a frameloader to start with.
