…n Rust 1.80
`std::mem::{size,align}_of{,_val}` was added to `std::prelude` in Rust
1.80; see
[`rust`#123168](rust-lang/rust#123168).
However, we don't have an MSRV at 1.80 or higher yet. So, let's work
around it by importing these items fully. Since neither `clippy` nor
`rustc` lint against shadowed `prelude` items yet (see also a [proposed
`clippy` lint] for such), that lets us remove the explicit `std::mem::*`
imports later at our leisure.
[proposed `clippy` lint]: rust-lang/rust-clippy#8439
