Refactor all remaning cases where the current zone is used through new(Isolate*) and remove this interface. Removing this interface is needed to move towards multiple threads per isolate, and also makes the caller more aware of the scope of the zone used, reducing the risk of use-after-free. Make the current thread and the stack zone created around native/runtime entries directly available in their body, saving an indirection (and optimized away if unused).
