Migrates tests to use internal module directly

Instead of the `unstable_concurrentAct` exports. Now we can drop those
from the public builds.

I put it in the jest-react package since that's where we put our other
testing utilities (like `toFlushAndYield`). Not so much so it can be
consumed publicly (nobody uses that package except us), but so it works
with our build tests.
