Render resolved streaming content for static render result

[huozhi]

• Fix the static streaming render result isn't the resolved streaming rendering content (resolve suspense)
• Update readable stream polyfill to fit the w3c standard

The significant change about the stream polyfill is delying the pull until getReader is called, so that react can delay the startFlowing work, otherwise it will start in onShellReady which leads to the streaming content is flushed too early
