Don't disappear layout effects unnecessarily (#25660)

Nested Offscreens can run into a case where outer Offscreen is revealed
while inner one is hidden in a single commit. This is an edge case that
was previously missed. We need to prevent call to disappear layout
effects.

When we go from state:
```jsx
<Offscreen mode={'hidden'}> // outer offscreen
  <Offscreen mode={'visible'}> // inner offscreen
    {children}
  </Offscreen>
</Offscreen>
```

To following. Notice that visibility of each offscreen flips.

```jsx
<Offscreen mode={'visible'}> // outer offscreen
  <Offscreen mode={'hidden'}> // inner offscreen
    {children}
  </Offscreen>
</Offscreen>
```

Inner offscreen must not call
`recursivelyTraverseDisappearLayoutEffects`.
Check unit tests for an example of this.
