This makes --inspect and stdin/out functional in the embedded snapshot,
currently it's not guaranteed that these work perfectly, the
plan is to investigate any out-of-sync states that might appear
in user land snapshots with this while the it is a configure-time
feature.

This adds a --build-snapshot runtime option which is currently only
supported by the node_mksnapshot binary, and a --node-snapshot-main
configure option that makes use it to run a custom script when
building the embedded snapshot. The idea is to have this experimental
feature in core as a configure-time feature for now, and investigate
the renaming V8 bugs before we make it available to more users via
making it a runtime option.

Instead of passing the snapshot blob, the per-isolate data
indices and the EnvSerializeInfo separately, use the aggregate
type Snapshot to carry these around, and refactor
NodeMainInstance so that it owns the v8::Isolate::CreateParams
when it owns its isolate. This also gets rid of the owns_isolate_
and deserialize_mode_ booleans in NodeMainInstance since
NodeMainInstance can compute these by just checking if it has
pointers to the CreateParams or the SnapshotData.

Put the hrtime backing store in the process methods binding data
so that it can be integrated into the snapshot builder. For
now we simply discard the contents of the hrtime buffer during
serialization and create new buffers upon deserialization because
the contents are only useful in a synchronous call.
This also moves the helper function for creating V8 FastAPI methods
into `Environment::SetFastMethod()` for code reuse. The v8::CFunction
need to be created before the Environment is created so that we
have the CTypeInfo address available for external reference
registration.

This is only necessary for the snapshot builder (because we
have no way to resurrect the handles at the moment). In addition,
print the handles if the debug flag is set or if the queues
are not empty after snapshot is created.

This patch:
- Moves the snapshot building code to src/ so that we can reuse it
later when generating custom snapshots from an entry point accepted
by the node binary.
- Create a SnapshotData struct that incorporates all the data useful
for a snapshot blob, including both the V8 data and the Node.js
data.

Use a virtual function in order to save space (8 bytes per instance
on 64-bit platforms) and in order to be consistent with the other
methods on BaseObject.

This patch adds the SnapshotableObject interface. Native objects
supporting serialization can inherit from it, implementing
PrepareForSerialization(), Serialize() and Deserialize()
to control how the native states should be serialized and
deserialized.
