MaybeUninit::zeroed() is handy, but it introduces unsafe (and has a pretty heavy syntax in general). Introduce a trait that provides the same functionality while staying within safe Rust. In addition, MaybeUninit::zeroed() is not available as a "const" function until Rust 1.75.0, so this also prepares for having handwritten implementations of the trait until we can assume that version.
