This patch implement a mkcodecache executable on top of the `NativeModuleLoader` singleton. This makes it possible to build a Node.js binary with embedded code cache without building itself using the code cache stub - the cache is now initialized by `NativeModuleEnv` instead which can be refactored out of the mkcodecache dependencies.
