TabGroup never really made any difference in which thread something go
dispatched to. This was the intended use, but development of TabGroups
with abstract main threads never made it that far. The good thing is
that thish makes it safe to also remove to the SystemGroup and instead
switch all SystemGroup dispatches to dispatches to main thread.
Timers for setTimeout and workers were the sole users of wrapped and
throttled event targets, that those throttled queues have been moved
to the BrowsingContextGroup and are now accessed explicitly.
The SchedulerEventTarget has been removed, since there are no longer a
separate event target for every TaskCategory. Instead a
LabellingEventTarget has been added to DocGroup to handle the case
where an event is dispatched do DocGroup or when an AbstractThread is
created using a DocGroup. This means that we'll actually label more
events correctly with the DocGroup that they belong to.
DocGroups have also been moved to BrowsingContextGroup.

I had to fix four things:
* I needed to move <utility> back down in GuardObjects.h because I was hitting
obscure problems with our system include wrappers like this:
0:03.94 /usr/include/stdlib.h:550:14: error: exception specification in declaration does not match previous declaration

Which I really didn't feel like digging into.
* I had to restore the order of TrustOverrideUtils.h and related files in nss
because the .inc files depend on TrustOverrideUtils.h being included earlier.
* I had to add a missing include to RollingNumber.h
* Also had to partially restore include order in JsepSessionImpl.cpp to avoid
some -WError issues due to some static inline functions being defined in a
header but not used in the rest of the compilation unit.

Add browser support for FinalizationGroup by setting the HostCleanupFinalizationGroupCallback in CycleCollectedJSContext. The callback adds groups pending cleanup to a vector stored in a PersistentRooted. A runnable is dispatched to call back into the JS engine and perform cleanup at a later time as a separate task. Using AutoEntryScript reports errors to the console.

We are getting this exception because we return false here and do not perform
the microtask checkpoint when CycleCollectedJSContext::runJobs executes, but
the contract of runJobs() _requires_ that the microtask queue be empty after
is has completed execution.
CycleCollectedJSContext::RecursionDepth() returns the depth taking the debugger
recursion depth and the thread recursion depth into account, however when
used here, mTargetedMicroTaskRecursionDepth is expects to only be compared
against the thread recursion depth

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Define a new RAII class, AutoDebuggerJobQueueInterruption, to save and restore
the current ECMAScript job queue, to protect the debuggee's job queue from
activity that occurs in debugger callbacks. Add a new method to the JS::JobQueue
abstract base class, saveJobQueue, to support AutoDebuggerJobQueueInterruption.
Comments on AutoDebuggerJobQueueInterruption provide details.
Implement saveJobQueue for SpiderMonkey's internal job queue and for Gecko's job
queue in CycleCollectedJSContext.

While the behavior of ECMAScript Promises and their associated job queue is
covered by the ECMAScript standard, the HTML specification amends that with
additional behavior the web platform requires. To support this, SpiderMonkey
provides hooks the embedding can set to replace SpiderMonkey's queue with its
own implementation.
At present, these hooks are C-style function-pointer-and-void-pointer pairs,
which are awkward to handle and mistake-prone, as passing a function the wrong
void* is not a type error. Later patches in this series must add new hooks,
making a bad situation worse.
A C++ abstract base class is a well-typed alternative. This introduces a new
`JS::JobQueue` abstract class, and adapts SpiderMonkey's internal job queue and
Gecko's customization to use it. `GetIncumbentGlobalCallback` and
`EnqueuePromiseJobCallback` become virtual methods.
Within SpiderMonkey, the patch gathers the various fields of JSContext that
implement the internal queue into their own type, js::InternalJobQueue. Various
jsfriendapi functions become veneers for calls to methods specific to the
derived class. The InternalJobQueue type itself remains private to SpiderMonkey,
as it uses types like TraceableFifo, derived from Fifo, that are not part of
SpiderMonkey's public API.
Within Gecko, CycleCollectedJSContext acquires JS::JobQueue as a private base
class, and a few static methods are cleaned up nicely.
There are a few other hooks defined in js/public/Promise.h that might make sense
to turn into virtual methods on JobQueue. For example,
DispatchToEventLoopCallback, used for resolving promises of results from
off-main-thread tasks, is probably necessarily connected to the JobQueue
implementation in use, so it might not be sensible to set one without the other.
But it was left unchanged to reduce this patch's size.

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.
