Currently we fail to properly handle shadowed properties. If the
receiver defines a non-enumerable property that reappears on the
prototype as enumerable it incorrectly shows up in [[Enumerate]].
By extending the KeyAccumulator to track non-enumerable properties
we can now properly filter them out when seeing them further up in
the prototype-chain.

In particular, return Maybe<bool> from any function that can throw, and
use MAYBE_RETURN and RETURN_FAILURE macros consistently where applicable.
No change in behavior intended.

Split out of PropertyAttributes, and used for all filtering purposes.
Also moved PropertyAttributes into the v8::internal:: namespace.
No change in behavior intended.

Both are integrated into JSReceiver::GetKeys().
For now, the implementation ignores Symbol/DONT_ENUM filtering.
