Offer a C FFI for Node.js embedders

What is the problem this feature will solve?

Node.js is prolific throughout the server-side world with many projects wanting to repackage the Node.js runtime and the associated standard library/resolution logic/Node.js-isms to offer it to customers such that they can reuse their existing tooling/dependencies.

Notable examples of this:

• Rspack
• Esbuild
• Parcel
• Supabase
• AWS Lambda
• etc

Currently, Node.js cannot be embedded in languages that only support native libraries with a C FFI (Rust, Dotnet, Go, etc).

This leads project maintainers to look for alternative embeddable runtimes that have incomplete Nodejs support, notably Deno (which is a great project in its own right, but lacks certain features that would necessitate consumers rewriting project code).

What is the feature you are proposing to solve the problem?

• Expose Node.js embedding capabilities via a C FFI
• Offer a static library to allow including Node.js within the embedding binary

What alternatives have you considered?

• Embedding Deno
• Removing the "Deno" parts of Deno and maintaining a light version with a focus on supporting the Node.js standard library
• Maintaining a fork of Nodejs with a C FFI
  • With Rust bindings
