Node.js built-in module support in the vm context

Scripts/Modules running in the context created with `vm.createContext` can not access various Node.js built-in apis/modules like `URL`, `node:assert`, `node:http`, etc. This makes it cumbersome to create a disposable context for use cases like hot-module-reload to run existing node.js apps. We can provide a built-in API to create a `context` (or a new `NodeRealm` for compatibility) with full-fledged Node.js built-in modules support. It allows object exchanges between realms and shares the same loop with the main context. , similar to the existing `vm.context`. /cc @mcollina @nodejs/realm @nodejs/vm
