Stacked on #30899. This adds another map to store Server Components logs. When they're replayed with an owner we can associate them with a DevToolsInstance. The replaying should happen before they can mount in Fiber so they'll always have all logs when they mount. There can be more than one Instance associated with any particular ReactComponentInfo. It can also be unmounted and restored later. One thing that's interesting about these is that when a Server Component tree refreshes a new set of ReactComponentInfo will update through the tree and the VirtualInstances will update with new instances. This means that the old errors/warnings are no longer associated with the VirtualInstance. I.e. it's not continually appended like updates do for Fiber backed instances. On the client we dedupe errors/warnings for the life time of the page. On the server that doesn't work well because it would mean that when you refresh the page, you miss out on warnings so we dedupe them per request instead. If we just appended on refresh it would keep adding them. If ever add a deduping mechanism that spans longer than a request, we might need to do more of a merge when these updates. Nothing actually adds logs to this map yet. That will need an integration with Flight in a follow up.
