Rename Node SSR Callbacks to onShellReady/onAllReady and Other Fixes (#24030)

* I forgot to call onFatalError

I can't figure out how to write a test for this because it only happens
when there is a bug in React itself which would then be fixed if we found
it.

We're also covered by the protection of ReadableStream which doesn't leak
other errors to us.

* Abort requests if the reader cancels

No need to continue computing at this point.

* Abort requests if node streams get destroyed

This is if the downstream cancels is for example.

* Rename Node APIs for Parity with allReady

The "Complete" terminology is a little misleading because not everything
has been written yet. It's just "Ready" to be written now.

onShellReady
onShellError
onAllReady

* 'close' should be enough
