[metadata] only blocking render for html bots in ppr pages (#76379) ### What In non-PRR mode, we keep the original behavior that metadata is blocking but stream the rest. Previously we also do the full dynamic rendering for both non-PPR and PPR pages, which is required for PPR pages to discard the postpone cache but not necessary for non-PPR pages. This PR align the behavior as before. Closes NDX-881
