  -----------
  [WebIDL] Default toJSON() method should create result object in its realm
https://bugs.webkit.org/show_bug.cgi?id=244939

Reviewed by NOBODY (OOPS!).

Per ECMA-262 [1], %Object.prototype% notation points to current realm, which
is the realm of toJSON() function [2], and not the relevant one.

Aligns WebKit with Blink and Gecko.
