Fix checkbox and radio hydration (#27401)
Fixes whatever part of #26876 and vercel/next.js#49499 that #27394 didn't fix, probably. From manual tests I believe this behavior brings us back to parity with latest stable release (18.2.0). It's awkward that we keep the user's state even for controlled inputs, so the DOM is out of sync with React state. Previously the .defaultChecked assignment done in updateInput() was changing the actual checkedness because the dirty flag wasn't getting set, meaning that hydrating could change which radio button is checked, even in the absence of user interaction! Now we go back to always detaching again. DiffTrain build for [db69f95](db69f95)
