Dan Abramov e23673b511 [Flight] Add getCacheForType() to the dispatcher (#20315 )

* Remove react/unstable_cache

We're probably going to make it available via the dispatcher. Let's remove this for now.

* Add readContext() to the dispatcher

On the server, it will be per-request.

On the client, there will be some way to shadow it.

For now, I provide it on the server, and throw on the client.

* Use readContext() from react-fetch

This makes it work on the server (but not on the client until we implement it there.)

Updated the test to use Server Components. Now it passes.

* Fixture: Add fetch from a Server Component

* readCache -> getCacheForType<T>

* Add React.unstable_getCacheForType

* Add a feature flag

* Fix Flow

* Add react-suspense-test-utils and port tests

* Remove extra Map lookup

* Unroll async/await because build system

* Add some error coverage and retry

* Add unstable_getCacheForType to Flight entry

README.md

The error code system substitutes React's error messages with error IDs to provide a better debugging support in production. Check out the blog post here.

codes.json contains the mapping from IDs to error messages. This file is generated by the Gulp plugin and is used by both the Babel plugin and the error decoder page in our documentation. This file is append-only, which means an existing code in the file will never be changed/removed.
extract-errors.js is an node script that traverses our codebase and updates codes.json. You can test it by running yarn extract-errors.
transform-error-messages is a Babel pass that rewrites error messages to IDs for a production (minified) build.
