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.

Inizia dal punto di ingresso vm.SourceTextModule e dal comportamento di risoluzione dei moduli di Node indicato nell’issue. Esamina i valori predefiniti richiesti per linker, initializeImportMeta e importModuleDynamically, inclusa la configurazione di root, della cache dei moduli e dei moduli integrati. Il lavoro è completato quando i vm.Modules comuni possono usare implementazioni integrate senza callback personalizzati.
