Benedikt Meurer 2b94e5677f [inspector] Report [[Prototype]] as internal property. 
Previously the inspector was trying to add a special `__proto__`
property to every JSObject, which looked and behaved like a real
data property on the object. But this is confusing to developers
since `__proto__` is not a real data property, but usually an
accessor property on the `Object.prototype`.

Additionally all other internal properties are reported using the
[[Name]] notation, with the [[Prototype]] having been the strange
outlier.

Drive-by-cleanup: Use an ArrayList to collect the name/value pairs
inside Runtime::GetInternalProperties(), which makes this function
more readable and easier to add things.
