[json] Allow any callable object for toJSON.

[json] Allow any callable object for toJSON.

Previously only JSFunctions seemed to be valid for toJSON, which doesn't
match the ES6 specification that allows any object with [[Call]]
internal method (i.e. any Callable in V8 terminology), including bound
functions and proxies.

Hey Yang,

Quickfix for toJSON checking in C++ land (the JS version was already fixed for
whatever reason).
Please take a look.

Thanks,
Benedikt
