Revert of [proxies] Better print for proxies in d8 (patchset #6 id:100001 of https://codereview.chromium.org/1530293004/ )

Reason for revert:
needs --allow-natives-syntax

Original issue's description:
> [proxies] Better print for proxies in d8
>
> Function proxies would not be printed so far since they ended up in Function.prototype.toString which only works with Function as a receiver but no Proxy. Additionally added support for more gracefully dealing with recursive __proto__ structures introduced by proxies.
