[DevTools] Don't capture durations for disconnected subtrees when profiling (#35718)

After https://github.com/facebook/react/pull/34089, when updating
(possibly, mounting) inside disconnected subtree, we don't record this
as an operation. This only happens during reconnect. The issue is that
`recordProfilingDurations()` can be called, which diffs tree base
duration and reports it to the Frontend:

65db1000b9/packages/react-devtools-shared/src/backend/fiber/renderer.js (L4506-L4521)

This operation can be recorded before the "Add" operation, and it will
not be resolved properly on the Frontend side.

Before the fix:
```
commit tree › Suspense › should handle transitioning from fallback back to content during profiling

    Could not clone the node: commit tree does not contain fiber "5". This is a bug in React DevTools.

      162 |     const existingNode = nodes.get(id);
      163 |     if (existingNode == null) {
    > 164 |       throw new Error(
          |             ^
      165 |         `Could not clone the node: commit tree does not contain fiber "${id}". This is a bug in React DevTools.`,
      166 |       );
      167 |     }
