Revert "[Re-land] Make prerendering always non-blocking (facebook#31268)" (facebook#31355)

This reverts commit 6c4bbc7.

It looked like the bug we found on the original land was related to
broken product code. But through landing facebook#31268 we found additional bugs
internally. Since disabling the feature flag does not fix the bugs, we
have to revert again to unblock the sync. We can continue to debug with
our internal build.
