Allow runtime to handle CJS

[yorinasub17]

Right now, the runtime only works with ESM code and ESM node modules (specifically, node modules that specify a module attr in the package.json). For better compatibility, we should add support CJS by adding in the CJS translation layer.

This can be implemented using https://github.com/denoland/deno/blob/9010b8df53cd37f0410e08c43a194667974686a2/ext/node/analyze.rs#L44

However, implementing this requires some dependency injection, namely the CJS analyzer and FS.
