CL [1] has prevented gin from recreating wrappers after GC,
so doesn't fire timer if its wrapper is empty otherwise it will
be crashed.

I'll extend the file to talk about how to use gin without the rest of
chromium, and add examples of how to startup V8, and how to wrap C++
objects.

Add an Arguments::GetAll() function that returns all arguments as a
std::vector<v8::Local<v8::Value>>. This is more clear, concise, and
slightly more performant than the alternative of using
Arguments::GetRemaining() since it doesn't require trying to convert
and avoids unnecessary calls.

Add a test for the new method.

Reverted due to a compile error, now fixed.

This changes gin::Wrappable to track its cleanup
state in order to prevent async operations from
recreating a wrapper between first and second weak
callbacks.

GetWrapper is changed to return a MaybeLocal,
and callers are updated accordingly; checking
in some cases and failing gracefully in others.

Mojo JS's WaitingCallback is changed to silently
ignore handle notifications if its wrapper is
no longer alive.

features::kV8NoTurbo is defined in //gin:gin_features. Since this is a

targets it must be a component instead of a source_set to avoid multiple

Currently, in order to get at the creation context of the holder, one
has to do the following:
v8::Local<v8::Object> holder;
arguments->GetHolder(&holder);
v8::Local<v8::Context> context = holder->CreationContext();

This isn't terrible, but it's a little verbose when all we really want
is FunctionCallbackInfo::Holder::CreationContext(). Add a method to get
at it directly.

This change requires the user of LazyInstance to explicitly select
either ::DestructorAtExit or ::Leaky. It seems clear that many users of
LazyInstance have just gone with default and are either unaware or
didn't consider that the default requires running an AtExit at process
shutdown.

As a first step, make this choice explicit, and update current users
to be ::DestructorAtExit to maintain current behaviour. Follow ups can
then attempt to consider individual switches from DestructorAtExit to
Leaky including reviewers with domain-specific knowledge.

i.e. No intended behaviour change from this CL.

When run benchmarks on Android, we don't get runtime statistics result because
we register an observer to trigger a flag to enable it, however, tracing is
started before observers are added to observer list in this case, thus we force
to fire observer when we register an observer through platform API when
recording is in progress.

Some utility processes need to initailize Blink and V8, and V8
initialization now assumes the main thread provides a scheduler; but
a utility process' main thread does not in fact provide one.

This eliminates the recently introduced assumption of a non-null scheduler,
defaulting to the previous behavior (using the current ThreadTaskRunnerHandle)
when no scheduler is provided.
