[json] Replace JSArray with std::vector to track circular structures

This CL prepares JSON#stringify for improved error messages when
serializing circular structures. To this end, we also push the
key/index, in addition to the object itself, onto the stack that keeps
track of circular structures.

The stack itself is changed from a JSArray to a std::vector.
