v8: expose new V8 serialization API

Expose the new serialization API that was added in V8 5.5 to userland.
The JS API is virtually a direct copy of what V8 provides on the
C++ level.

This is useful Node as a possible replacement for some internals
that currently use JSON, like IPC, but is likely to be useful to
general userland code as well.
