This adds an internal property [[IsDetached]] to the inspector preview of ArrayBuffer instances, which indicates whether the ArrayBuffer was detached (i.e. transfered via `postMessage`). Previously it was rather impossible to tell whether an ArrayBuffer was detached, you had to know that V8 violates the ECMAScript specification and simply sets the byteLength accessor to 0 upon detaching an ArrayBuffer (but even then it was still impossible to tell whether that ArrayBuffer wasn't simply an empty one from the get go).
