These are the only ones marked with PerformedWork atm anyway. This lets us customize the logging for each branch.
Ideally we'd be able to mark the component that errored but we don't commit the failed tree. In principle we could maybe walk the work in progress.
We also keep track of the errors and log those.

This is similar to #31876 but for Server Components. It marks them as errored and puts the error message in the Summary properties. <img width="1511" alt="Screenshot 2024-12-20 at 5 05 35 PM" src="https://github.com/user-attachments/assets/92f11e42-0e23-41c7-bfd4-09effb25e024" /> 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.

This tracks commit phase errors and marks the component that errored as red. These also get the errors attached to the entry.
In the render phase I just mark the Error Boundary that caught the error. We don't have access to the actual error since it's locked behind closures in the update queue. We could probably expose that someway.
Follow ups:
Since the Error Boundary doesn't commit its attempted render, we don't log those. If we did then maybe we should just mark the errored component like I do for the commit phase. We could potentially walk the list of errors and log the captured fibers and just log their entries as children.
We could also potentially walk the uncommitted Fiber tree by stashing it somewhere or even getting it from the alternate. This could be done on Suspense boundaries too to track failed hydrations.
