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.

Introduce APIs that allow for the creation of JavaScript strings without
copying the underlying native string into the engine. The APIs fall back
to regular string creation if the engine's external string APIs are
unavailable. In this case, an optional boolean out-parameter indicates
that the string was copied, and the optional finalizer is called if
given.
