fix Zip unsoundness (again)
Some history: The Zip TrustedRandomAccess specialization has tried to emulate the side-effects of the naive implementation for a long time, including backwards iteration. 82292¹ tried to fix unsoundness (82291¹) in that side-effect-preservation code, but this introduced some panic-safety unsoundness (86443¹), but the fix 86452¹ didn't fix it for nested Zip iterators (137255¹). Rather than piling yet another fix ontop of this heap of fixes this PR reduces the number of cases in which side-effects will be preserved; the necessary API guarantee change was approved in 83791¹ but we haven't made use of that so far. ¹ see merge commit for linkfied issues.
