n-api: add APIs for per-instance state management 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.

n-api: free instance data as reference Instance data associated with a `napi_env` is no longer stored on the env itself but is instead rendered as a reference. Since `v8impl::Reference` is tied to a JS object, this modification factors out the `v8impl::Reference` refcounting and the deletion process into a base class for `v8impl::Reference`, called `v8impl::RefBase`. The instance data is then stored as a `v8impl::RefBase`, along with other references, preventing a segfault that arises from the fact that, up until now, upon `napi_env` destruction, the instance data was freed after all references had already been forcefully freed. If the addon freed a reference during the `napi_set_instance_data` finalizer callback, such a reference had already been freed during environment teardown, causing a double free.
