Add an ExitCode enum class and use it throughout the code base
instead of hard-coding the exit codes everywhere. At the moment,
the exit codes used in many places do not actually conform to
what the documentation describes. With the new enums (which
are also available to the JS land as constants in an internal
binding) we could migrate to a more consistent usage of the
codes, and eventually expose the constants to the user land
when they are stable enough.

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.

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.

Add an ExternalReferenceRegistry class for registering static
external references.
To register the external JS to C++ references created in a binding
(e.g. when a FunctionTemplate is created):
- Add the binding name (same as the id used for `internalBinding()`
and `NODE_MODULE_CONTEXT_AWARE_INTERNAL`) to
`EXTERNAL_REFERENCE_BINDING_LIST` in `src/node_external_reference.h`.
- In the file where the binding is implemented, create a registration
function to register the static C++ references (e.g. the C++
functions in `v8::FunctionCallback` associated with the function
templates), like this:
```c++
void RegisterExternalReferences(
ExternalReferenceRegistry* registry) {
registry->Register(cpp_func_1);
}
```
- At the end of the file where `NODE_MODULE_CONTEXT_AWARE_INTERNAL` is
also usually called, register the registration function with
```
NODE_MODULE_EXTERNAL_REFERENCE(binding_name,
RegisterExternalReferences);
```

This addresses some long-standing TODOs by Joyee and me about
making the embedder API more powerful and us less reliant on
internal APIs for creating the main thread and Workers.

Make the calls `stop_sub_worker_contexts()`, `RunCleanup()`
part of the public API for easier embedding.
(Note that calling `RunAtExit()` is idempotent because the
at-exit callback queue is cleared after each call.)

This patch encapsulates the main isolate management into a
NodeMainInstance class that manages the resources with RAII
and controls the Isolate::CreateParams (which is necessary
for deserializing snapshots with external references)
