Previously the V8 inspector would only turn embedder accessors on the
prototype chain into data properties, but would not do the same for
ECMAScript builtins, which is kind of inconsistent and weird behavior.

This leaves in the hack that the inspector reports native accessor
properties as (own) data properties, but now at least the very least
does so consistently. In the absence of a better solution, we'll go
with this for now.
