Rollup merge of #81742 - sdroege:exact-size-iterator-correctness, r=kennytm
Add a note about the correctness and the effect on unsafe code to the `ExactSizeIterator` docs As it is a safe trait it does not provide any guarantee that the returned length is correct and as such unsafe code must not rely on it. That's why `TrustedLen` exists. Fixes https://github.com/rust-lang/rust/issues/81739
