Provide built-in implementations of module linker, initializeImportMeta, importModuleDynamically

Is your feature request related to a problem? Please describe.

When using vm.SourceTextModule we have to implement a linker, initializeImportMeta, and importModuleDynamically, even if we just want the default behavior of built-in module support. There are many subtle ways to get that wrong.

Describe the solution you'd like

Default implementations that do basically what built-in module support does:

• A linker function that:
  • Reads files from disk, within a specified root.
  • Uses Node module resolution as implemented for modules
  • Uses a specified module cache
  • initializeImportMeta that sets url property
  • By configuration, allows access to built-in modules.

Describe alternatives you've considered

Userland libraries can take the first cuts at easy-to-use vm.Modules, but I think something for common use cases should likely be included.

从 vm.SourceTextModule 入口点以及 issue 中引用的 Node 模块解析行为开始。处理 linker、initializeImportMeta 和 importModuleDynamically 所请求的默认值，包括 root、模块缓存和内置模块配置。完成的标准是常见的 vm.Modules 可以在不使用自定义回调的情况下使用内置实现。
