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.

Add a flag for each experimental feature to indicate its presence.
That way, if we compile with `NAPI_EXPERIMENTAL` turned on, we'll be
able to distinguish between what `NAPI_EXPERIMENTAL` used to mean on an
old version of the headers when compiling against such an old version,
and what it means on a new version of Node.js.

We had a few code snippets that were using a non-descriptive tag (e.g.
`console` or `text`), whereas the actual language it's using describes
it better, and improves the syntax highlighting. This commit also
removes non-necessary leading chars (e.g. `$`, `>`, or `%`) to make it
easier for readers to copy and paste to try the command themselves.
