Auto merge of #60445 - RalfJung:maybe-uninit, r=Centril
stabilize core parts of MaybeUninit and deprecate mem::uninitialized in the future (1.40.0). This is part of implementing https://github.com/rust-lang/rfcs/pull/1892. Also expand the documentation a bit. This type is currently primarily useful when dealing with partially initialized arrays. In libstd, it is used e.g. in `BTreeMap` (with some unstable APIs that however can all be replaced, less ergonomically, by stable ones). What we stabilize should also be enough for `SmallVec` (Cc @bluss). Making this useful for structs requires https://github.com/rust-lang/rfcs/pull/2582 or a commitment that references to uninitialized data are not insta-UB.
