Remove renderToStaticNodeStream (#28873)

Stacked on #28872 

renderToStaticNodeStream was not originally deprecated when
renderToNodeStream was deprecated because it did not yet have a clear
analog in the modern streaming implementation for SSR. In React 19 we
have already removed renderToNodeStream. This change removes
renderToStaticNodeStream as well because you can replicate it's
semantics using renderToPipeableStream with onAllReady or
renderToReadableStream with await stream.allready.
