* Remove redundant initial of isArray (#21163)
* Reapply prettier
* Type the isArray function with refinement support
This ensures that an argument gets refined just like it does if isArray is
used directly.
I'm not sure how to express with just a direct reference so I added a
function wrapper and confirmed that this does get inlined properly by
closure compiler.
* A few more
* Rename unit test to internal
This is not testing a bundle.

* Add onError option to Flight Server
The callback is called any time an error is generated in a server component.
This allows it to be logged on a server if needed. It'll still be rethrown
on the client so it can be logged there too but in case it never reaches
the client, here's a way to make sure it doesn't get lost.
* Add fatal error handling
As per Seb's comment in #20465, we need to do the same thing in React Native as we do in Relay.
When `parseModel` suspends because of missing dependencies, it will exit and retry to parse later. However, in the relay implementation, the model is an object that we modify in place when we parse it, so when we we retry, part of the model might be parsed already into React elements, which will error because the parsing code expect a Flight model. This diff clones instead of mutating the original model, which fixes this error.
* Move files
* Update paths
* Rename import variables
* Rename /server to /writer
This is mainly because "React Server Server" is weird so we need another
dimension.
* Use "react-server" convention to enforce that writer is only loaded in a server
