[Debug Tools] Introspect Promises in use() (#28297)
Alternative to #28295. Instead of stashing all of the Usables eagerly, we can extract them by replaying the render when we need them like we do with any other hook. We already had an implementation of `use()` but it wasn't quite complete. These can also include further DebugInfo on them such as what Server Component rendered the Promise or async debug info. This is nice just to see which use() calls were made in the side-panel but it can also be used to gather everything that might have suspended. Together with #28286 we cover the case when a Promise was used a child and if it was unwrapped with use(). Notably we don't cover a Promise that was thrown (although we do support that in a Server Component which maybe we shouldn't). Throwing a Promise isn't officially supported though and that use case should move to the use() Hook. The pattern of conditionally suspending based on cache also isn't really supported with the use() pattern. You should always call use() if you previously called use() with the same input. This also ensures that we can track what might have suspended rather than what actually did. One limitation of this strategy is that it's hard to find all the places something might suspend in a tree without rerendering all the fibers again. So we might need to still add something to the tree to indicate which Fibers may have further debug info / thenables. DiffTrain build for commit 7a32d71.
