This is much nicer than just treating exceptions as uncaught, and
enables reporting of exceptions from the internal C++ deserialization
machinery.

Enable JS wrapper objects to be used as transferable or cloneable
objects in `postMessage()` calls, by having them extend a C++-backed
class.
This requires a few internal changes:
- This commit adds the possibility for transferred objects to
read/write JS values at the end of the serialization/deserialization
phases.
- This commit adds the possibility for transferred objects to list
sub-transferables, e.g. typically the public JS wrapper class
would list its C++ handle in there.
- This commit adds usage of `BaseObject` in a few more places, because
now during deserialization weakly held objects can also be involved,
in addition to `MessagePort`s.

There is no reason for this to be in C++. Using JavaScript means that
the code is more accessible to more developers, which is important
for any Node.js feature. This also simplifies the code significantly
in some areas. On the technical side, this potentially also enables
making some of the file system operations that are involved
asynchronous.

Node codebase has evolved a lot in the more than 10 years of its
existence. As more features (and code) have been added, changed,
removed, it's sometimes hard to keep track of what gets used and what
not.

The C++ land `node::FatalException()` is not in fact fatal anymore.
It gives the user a chance to handle the uncaught exception
globally by listening to the `uncaughtException` event. This patch
renames it to `TriggerUncaughtException` in C++ to avoid the confusion.
In addition rename the JS land handler to `onGlobalUncaughtException`
to reflect its purpose - we have to keep the alias
`process._fatalException` and use that for now since it has been
monkey-patchable in the user land.
This patch also
- Adds more comments to the global uncaught exception handling routine
- Puts a few other C++ error handling functions into the `errors`
namespace
- Moves error-handling-related bindings to the `errors` binding.

Refactor the C++ code for creating `MessagePort`s to skip calling the
constructor and instead directly instantiating the `InstanceTemplate`,
and always throw an error from the `MessagePort` constructor.
This aligns behaviour with the web, and creating single `MessagePort`s
does not make sense anyway.

Rename the per-isolate message listener to `PerIsolateMessageListener`
and move it to `node_errors.cc` since it's part of the error
handling process. It also creates an external reference so it needs
to be exposed in `node_errors.h` for a snapshot builder to know.

This adds a flag to define the default behavior for unhandled
rejections. Three modes exist: `none`, `warn` and `strict`. The first
is going to silence all unhandled rejection warnings. The second
behaves identical to the current default with the excetion that no
deprecation warning will be printed and the last is going to throw
an error for each unhandled rejection, just as regular exceptions do.
It is possible to intercept those with the `uncaughtException` hook
as with all other exceptions as well.
This PR has no influence on the existing `unhandledRejection` hook.
If that is used, it will continue to function as before.
