Support subclassing API functions

Support subclassing API functions.

When instantiating a subclassed API function, the instance cache is avoided. There is currently no direct API yet to instantiate a Template while passing in a new.target. It probably makes sense to extend ObjectTemplate::NewInstance to accept a new.target, in line with Reflect.construct.
