DevTools wants to be able to detect async functions in order to print
their synopsis better in stack traces and tooltips. This patch provides a
simple method to do the check.

This patch gives the ability for the embedder to ask for the
module requests of a module, and to pass a ResolveCallback
into Module::Instantiate().
In d8, I've implemented a simple module_map that's used
along with this API to allow loading, compiling, instantiating,
and evaluating a whole tree of modules.
No path resolution is yet implemented, meaning that all
import paths are relative to whatever directory d8 runs
in. And no imports are linked to the exports of the
requested module.

The existing PropertyQueryCallback intercepts getOwnPropertyDescriptor, but
it returns only value and attributes, not the accessors. This
PropertyDescriptorCallback returns a descriptor similar to Ecma-262 6.2.4.
You can either set a PropertyQueryCallback or a PropertyDescriptorCallback,
but not both. When you set a callback for DefineProperty(), you can set a
PropertyDescriptorCallback but not a PropertyQueryCallback.

This restores the contract that all API methods that return Maybe<T> or
MaybeLocal<T> always throw an exception when they return nothing.
Since v8::ValueDeserializer::ReadHeader can now throw exceptions, it
needs a Local<Context> parameter so that it can set up execution state
(entering the context, etc.). The old method has been marked for
deprecation, but since this API is experimental I intend to remove it
as soon as I've removed the use from Blink.
value-serializer-unittest has been updated to expect an exception in
all decode failure cases.

With the Indexed/GenericNamedPropertyDefinerCallback it is possible to intercept Object.defineProperty() calls.
Requests that call JSReceiver::OrdinaryDefineOwnProperty() internally, also trigger the interceptor. This includes Object.freeze(), Object.preventExtensions(), and Object.seal().
As without this patch, the query interceptor triggers on
defineProperty, unless the definer callback
intercepts the request.

Suitably scary warnings attached, as this will yet evolve (notably to handle
host objects, which are not currently handled).
Unit tests adjusted to use the public version of ValueSerializer, eliminating
any need they have to access v8::internal.
With this, Blink can begin using this code experimentally behind a flag as it
develops.
