We define a new type called `node_api_nogc_env` as the `const` version of `napi_env` and `node_api_nogc_finalize` as a variant of `napi_finalize` that accepts a `node_api_nogc_env` as its first argument. We then modify those APIs which do not affect GC state as accepting a `node_api_nogc_env`. APIs accepting finalizer callbacks are modified to accept `node_api_nogc_finalize` callbacks. Thus, the only way to attach a `napi_finalize` callback, wherein Node-APIs affecting GC state may be called is to call `node_api_post_finalizer` from a `node_api_nogc_finalize` callback. In keeping with the process of introducing new Node-APIs, this feature is guarded by `NAPI_EXPERIMENTAL`. Since this feature modifies APIs already marked as stable, it is additionally guared by `NODE_API_EXPERIMENTAL_NOGC_ENV`, so as to provide a further buffer to adoption. Nevertheless, both guards must be removed upon releasing a new version of Node-API.
