Simplify vm.Module

One thing that comes up in user feedback about the vm.Module API is that it requires excessive boilerplate, as you can see in the example in the docs: https://nodejs.org/api/vm.html#class-vmmodule. I think that most users want a straightforward ESM equivalent to vm.Script, without needing to define a context or a custom function for linking; the default should be to link modules as Node itself normally does.
