[DevTools] Track DOM nodes to Fiber map for HostHoistable Resources (#30590)

Follow up from #30584.

You can already select a singleton or hoistable (that's not a resource)
in the browser elements panel and it'll select the corresponding node in
the RDT Components panel. That works because it uses the same mechanism
as event dispatching and those need to be able to receive events.
However, you can't select a resource. Because that's conceptually one to
many.

This keeps track of which fiber is acquiring which resource so we can
find all the corresponding instances.

E.g. now you can select the `<link rel="stylesheet">` in the Flight
fixture in the Element panel and then the component that rendered it in
the Components panel will be selected.

If we had a concept multi-selection we could potentially select all of
them. This similar to how a Server Component can be rendered in more
than one place and if we want to select all matching ones. It's kind of
weird though and both cases are edge cases.

Notably imperative preloads do have elements that don't have any
corresponding component but that's ok. So they'll just select `<head>`.
Maybe in dev we could track the owners of those.
