[Transition Tracing] Add Passive Flag Whenever Suspense Boundary Toggles #24339

Previously, we were only adding the passive flag when we add the Visibility flag, which is only set when we go from primary to fallback. Now, we add the passive flag BOTH when we go from primary to fallback and from fallback to primary.

An alternate solution is to add the passive flag in the same place as the visibility flag in the offscreen complete phase (rather than the suspense complete phase), but this feature is currently only for suspense, and offscreen can be used in different ways, so for now we add the passive flag only in the suspense component's complete phase. We might want to revisit this later when we think about how offscreen should work with transition tracing.
