Removes the implementations that depend on the user-definable trait Copy.

Only fix regressions to ensure merge in 1.55: Does not modify vec::IntoIter.


This PR applies the beta-1.53 backport #86222 (merged as part of #86225), a reduced version of #85874 that only fixes regressions, to master in order to avoid the need for further backports from 1.55 onwards. Beta-1.54 backport already happened with #87136. In case that #85874 gets merged quickly (within a week), this PR would be unnecessary.

Thanks! Let's go ahead and merge this first, since #85874 has more complicated changes to review.
