Rollup merge of #97506 - JohnTitor:stabilize-nonnull-slice-from-raw-parts, r=m-ou-se,the8472

Stabilize `nonnull_slice_from_raw_parts`

FCP is done: https://github.com/rust-lang/rust/issues/71941#issuecomment-1100910416
Note that this doesn't const-stabilize `NonNull::slice_from_raw_parts` as `slice_from_raw_parts_mut` isn't const-stabilized yet. Given #67456 and #57349, it's not likely available soon, meanwhile, stabilizing only the feature makes some sense, I think.

Closes #71941
