Rollup merge of #94536 - dtolnay:transmute, r=Manishearth

Move transmute_undefined_repr back to nursery again

This PR reapplies #94014, which was reverted unintentionally I think by #94329. The combination of https://github.com/rust-lang/rust-clippy/pull/8432 + https://github.com/rust-lang/rust-clippy/pull/8497 in clippy should prevent this from happening again.
