nsSystemInfo is initialzied at first page load. Actually, content process uses
sync IPC to get Android OS information. But now, we can use Java code even if
on content process, so we should use JNI directly instead of sync IPC.
Also, nsSystemInfo still has unused extern android_sdk_version that is for
HoneyComp's DNS hack. So let's remote it.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

This is a follow-up to the previous part, which actually changes one of
these callers to use Array<nsIIDRef> instead of [array] nsIIDPtr.
From doing this patch, it seems like we should consider changing
the type `nsIIDRef` to instead simply be `nsIID`, and treat it more like
the `AString` types from the POV of XPIDL. `nsIIDPtr` would then
continue to exist for backwards compatibility, but we can probably
remove almost all current consumers over time.

Currently the [ref] and [ptr] types share the same underlying
implementation. This is unfortunate, and can cause correctness problems
with outparam refs (as an example).
By using the same tools used to allow other larger objects (such as
jsid, nsTArray, and nsString) to be stored directly in the nsXPTCVariant
object, this patch directly stores the nsID in the nsXPTCVariant object
when calling from JS into C++.
Using this new strategy avoids an nsID* allocation every time we pass
one over XPConnect, and should also allow us to simplify callers.
In addition, some special casing is added to xpidl to make it possible
to use the nsid reference type objects directly inside of Array<T>,
which will allow us to remove `[array] nsIIDPtr` callers.

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.

This commit hooks up nsFrameLoader in the child process to use the
PRemoteFrame protocol to support remote iframes. This is only activated
when a special pref is set, and the iframe has a marker attribute on it.
For example:
<iframe fission/>
In the future, we should unify nsFrameLoader to operate on a common
interface between the parent process top-level browser, and child
process subframe case. This commit just adds a new member that can
be used instead of mRemoteBrowser, when appropriate. IsRemoteFrame()
will return true for both cases.
