Expose the %ObjProto_valueOf% intrinsic object to embedders

https://html.spec.whatwg.org/multipage/history.html#the-location-interface
HTML Location platform objects need to be initialized with using
the %ObjProto_valueOf% intrinsic object.

This patch exposes the %ObjProto_valueOf% intrinsic object to
embedders.

Example usage is: https://crrev.com/c/2102306
