The VM state is a property of the isolate, not the CPU profiler.
Having to create a v8::CpuProfiler instance in order to change
the property is somewhat inefficient.

"background" refers to a priority and is inappropriate to refer to
worker threads as many tasks posted to worker threads by v8 are in
fact high priority.
Also took advantage of this rename to make NumberOfWorkerThreads()
return an int instead of size_t. While it is never negative, int is
simpler and Google C++ style guide states to avoid unsigned integers in
such cases (ref. "On Unsigned Integers" @
https://google.github.io/styleguide/cppguide.html#Integer_Types).
The Chromium embedder for that call provided an int which was converted
to size_t for this override and most often casted back down to int on the
v8 side, adding churn, and readability overhead.

This patch allows the embedder to specify V8 wrapper for each embedder

embedder node. The resulting node will have the same properties as
the embedder node. If the wrapper node name has a tag, then the tag

to remove it without a deprecation period.

e.g. when streaming comilation gets aborted because the browser tab gets
refreshed, then we want to omit rejecting the promise. In an older CL
(https://crrev.com/c/876103) we omit rejecting the promise when the
exception value is null. With this CL the exception value is a MaybeLocal
so that we document properly that the value can be null. In addition, I
added documentation to say that in that case we do not reject the promise.

This implements the ideas outlined in the section "Microtask queue"
of the exploration document "Promise and async/await performance" (at
https://goo.gl/WHRar2), except that the microtask queue stays a linear
FixedArray for now, to avoid running into trouble with the parallel
scavenger. This way we can already save a significant amount of
allocations, thereby reducing the GC frequency quite a bit.
All items on the microtask queue are now proper structs that subclass
Microtask, i.e. we also wrap JSFunction and MicrotaskCallback jobs
into structs. We also consistently remember the context for every
microtask (except for MicrotaskCallback where we don't have a
context), and execute it later in exactly that context (as required
by the spec anyways for the Promise related jobs). Particularly
interesting is the PromiseReactionJobTask and its subclasses, since
they are designed to have the same size as the PromiseReaction. When
we resolve a JSPromise we just take the existing PromiseReaction
instances and morph them into PromiseFulfillReactionJobTask or
PromiseRejectReactionJobTask (depending whether you "Fulfill" or
"Reject"). That way the JSPromise class is now only 6 words instead
of 10 words.
Also the PromiseReaction and the reaction tasks can either carry a
JSPromise (for the fast native case) or a PromiseCapability (for the
generic case), which means we don't always pay the overhead of having
to also remember the "deferred resolve" and "deferred reject" handlers
that are only relevant for the generic case anyways.
It also fixes a spec violation where we called "then" before we actually
enqueued the PromiseResolveThenableJob, which is observably wrong.
Calling it later has the advantage that it should be fairly
straight-forward now to completely avoid it for native Promise
instances.
This seems to save around 10-20% on the various Promise benchmarks and
micro-benchmarks. We expect to gain even more as we're now able to
inline various operations into TurboFan optimized code easily.

The chromium callers were updated in https://crrev.com/c/868287,
while the pdfium callers were updated in
https://pdfium-review.googlesource.com/c/pdfium/+/23058.
As a precaution to avoid a repeat of https://crbug.com/803330,
I've manually built pdfium, along with the additional gn flag
"pdf_enable_xfa = true".

Now that write-protection of code memory is enabled everywhere and V8 is
fully W^X compliant, we can remove the permission mode in question.
