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](https://github.com/alshdavid/libnode-prebuilt) - [With Rust bindings](https://github.com/alshdavid/libnode_sys)
