Convert more Suspense tests to use act (2/n) (#26610)
Many of our Suspense-related tests were written before the `act` API was introduced, and use the lower level `waitFor` helpers instead. So they are less resilient to changes in implementation details than they could be. This converts some of our test suite to use `act` in more places. I found these while working on a PR to expand our fallback throttling mechanism to include all renders that result from a promise resolving, even if there are no more fallbacks in the tree. I think this covers all the remaining tests that are affected.
