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.

首先阅读现有的 vm.createContext API，以及 issue 对 Node.js 内置模块的引用，包括 URL、node:assert 和 node:http。定义新 context 或 NodeRealm 将如何提供对内置模块的访问、realm 之间的对象交换以及共享事件循环；该 issue 未指定实现文件或测试。
