Maybe it's better if we close #71941 and move tracking of the const part to the const_slice_from_raw_parts issue.

…rom-raw-parts, r=m-ou-se,the8472 Stabilize `nonnull_slice_from_raw_parts` FCP is done: rust-lang#71941 (comment) Note that this doesn't const-stabilize `NonNull::slice_from_raw_parts` as `slice_from_raw_parts_mut` isn't const-stabilized yet. Given rust-lang#67456 and rust-lang#57349, it's not likely available soon, meanwhile, stabilizing only the feature makes some sense, I think. Closes rust-lang#71941
