The V8 API provides interceptors. They are not part of the
EcmaScript specification. But their behavior should be consistent.
For example, when an EnumeratorInterceptor is defined, Object.keys(),
Object.entries(), and Object.values() should all have the
same number of entries.

This CL creates consistent behavior among these
functions. If a QueryCallback is present, it is used to
filter the result from the EnumeratorCallback for
enumerable properties.
