tools: implement mkcodecache as an executable

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.
