[DevTools] Show suspended by subtree from Activity to next Suspense boundary (#34438)

Stacked on #34435.

This adds a method to get all suspended by filtered by a specific
Instance. The purpose of this is to power the feature when you filter by
Activity. This would show you the "root" within that Activity boundary.

This works by selecting the nearest Suspense boundary parent and then
filtering its data based on if all the instances for a given I/O info is
within the Activity instance. If something suspended within the Suspense
boundary but outside the Activity it's not included even if it's also
suspending inside the Activity since we assume it would've already been
loaded then.

Right now I wire this up to be a special case when you select an
Activity boundary same as when you select a Suspense boundary in the
Components tab but we could also only use this when you select the root
in the Suspense tab for example.
