Closure Serializer

This is a fork of the Pulumi Closure Serializer. @pulumi/pulumi.

Motivation

Functionless allows developers to write cloud applications (using aws-cdk) with pure typescript.

``ts
const sfn = new StepFunction(stack, "sfn", () => {
/ something in the state machine /
return "result";
});

new Function(stack, "func", async () => {
return sfn();
});
`

Pulumi's closure serializer helped us bootstrap this experience by doing the heavy lifting of runtime data serialization.

However, Pulumi's serializer had a few short comings:

1. Coupled to the whole @pulumi/pulumi npm package
2. Limited extensibility
3. Makes use of Pulumi resources (Logging and Secrets) in the serializer

Changes from Pulumi

- Bug Fix: Symbol Support
- Removed: Pulumi Secret support
- Removed: Pulumi Logging support
- Change: serialize function support replacement of runtime data to be serialized on top of avoiding serialization
- Change: Do not serialize functions and constructors that are not invoked
- Change: Anonymous functions can be injected at runtime through the serialize callback.
- Change: Allow for TypeScript TransformerFactory functions to be applied to serialized closures.
- Change: Replace the with syntax with simple let` statements.
