Adds `napi_set_instance_data()` and `napi_get_instance_data()`, which allow native addons to store their data on and retrieve their data from `napi_env`. `napi_set_instance_data()` accepts a finalizer which is called when the `node::Environment()` is destroyed. This entails rendering the `napi_env` local to each add-on.
