PR #125443 will reformat all the use declarations in the repo. This would break a patch kept in `rustc_codegen_cranelift` that gets applied to `library/std/src/sys/pal/windows/rand.rs`. So this commit formats the use declarations in `library/std/src/sys/pal/windows/rand.rs` in advance of #125443 and updates the patch file accordingly. The motivation is that #125443 is a huge change and we want to get fiddly little changes like this out of the way so it can be nothing more than an `x fmt --all`.
