This will allow the devtools UI to display private fields on the scope panel. Instead of extending GetInternalProperties, we expose a separate GetPrivateFields method on the debug interface. This allows us to do better type checking, for example, we can directly cast to a v8::Private as this can only contain private fields. This also allows us to have better constraints on the input type -- v8::Object, as opposed to a v8::Value. The KeyAccumulator is extended to collect private names for the PRIVATE_NAMES_ONLY PropertyFilter.

This CL fixes the check for empty elements in keys.cc. Previously we would accidentally bail out of the fast path because the check would always fail. As a consequence for-in loops that would initialize the enum-cache of an object with own-only fast properties would never be optimized properly.

This CL fixes a long-standing bug with Object.keys where the enumerability check was omitted if the [ownKeys] trap is not present. The only distinction the KeyAccumulator needs is whether it collects keys for for-in (is_for_in_) or not. ForInFilter performs a separate step to filter out non-enumerable keys later-on while in all the other use-cases we have to filter keys.

The Great Keys Migration: This is part of a bigger effort to centralize optimizations for key collections in a central place. This necessary to avoid the penalty that would be introduced by fixing shadowed property iteration.

With the recent spec change removing the [[Enumerate]] internal method, we now have to walk the complete prototype chain. This implies that we call the [[GetPrototypeOf]] trap on proxies. As a secondary change we now trigger the [[GetOwnProperty]] trap for the for-in filter step to see whether the properties are still enumerable. Before we did this in the key-accumulation phase. This way we slightly reduce the number of traps invoked. Whilst this is not ideal, it comes closer to the Spec's example implementation.

Introducing the KeyAccumulator accidentally removed some crucial fast-paths. This CL starts rewriting the KeyAccumulator, step-by-step introducing the special cases again.
