vm: remove MISSING_ARGS error code

The documentation states:

> This is only used for strict compliance with the API specification
> (which in some cases may accept func(undefined) but not func()). In
> most native Node.js APIs, func(undefined) and func() are treated
> identically, and the ERR_INVALID_ARG_TYPE error code may be used
> instead.
