[Flight] Mark Errored Server Components (facebook#31879)

This is similar to facebook#31876 but for Server Components.

It marks them as errored and puts the error message in the Summary
properties.

This only looks at the current chunk for rejections. That means that
there might still be promises deeper that rejected but it's only the
immediate return value of the Server Component that's considered a
rejection of the component itself.
