* First pass at scaffolding out the Node implementation of react-data.
While incomplete, this patch contains some changes to the react-data
package in order to start adding support for Node.
The first part of this change accounts for splitting react-data/fetch
into two discrete entries, adding (and defaulting to) the Node
implementation.
The second part is sketching out a rough approximation of `fetch` for
Node. This implementation is not complete by any means, but provides a
starting point.
* Remove NodeFetch module and put it directly into ReactDataFetchNode.
* Replaced react-data with react-fetch.
This patch shuffles around some of the scaffolding that was in
react-data in favor of react-fetch. It also removes the additional
"fetch" package in favor of something flatter.
* Tweak package organization
* Simplify and add a test

We've been shipping unprefixed experimental APIs (like `createRoot` and
`useTransition`) to the Experimental release channel, with the rationale
that because these APIs do not appear in any stable release, we're free
to change or remove them later without breaking any downstream projects.
What we didn't consider is that downstream projects might be tempted to
use feature detection:
```js
const useTransition = React.useTransition || fallbackUseTransition;
```
This pattern assumes that the version of `useTransition` that exists in
the Experimental channel today has the same API contract as the final
`useTransition` API that we'll eventually ship to stable.
To discourage feature detection, I've added an `unstable_` prefix to
all of our unstable APIs.
The Facebook builds still have the unprefixed APIs, though. We will
continue to support those; if we make any breaking changes, we'll
migrate the internal callers like we usually do. To make testing easier,
I added the `unstable_`-prefixed APIs to the www builds, too. That way
our tests can always use the prefixed ones without gating on the
release channel.
