Unrolled build for rust-lang#130403

Rollup merge of rust-lang#130403 - eduardosm:stabilize-const_slice_from_raw_parts_mut, r=workingjubilee Stabilize `const_slice_from_raw_parts_mut` Stabilizes rust-lang#67456, since rust-lang#57349 has been stabilized. Stabilized const API: ```rust // core::ptr pub const fn slice_from_raw_parts_mut<T>(data: *mut T, len: usize) -> *mut [T]; // core::slice pub const unsafe fn from_raw_parts_mut<'a, T>(data: *mut T, len: usize) -> &'a mut [T]; // core::ptr::NonNull pub const fn slice_from_raw_parts(data: NonNull<T>, len: usize) -> Self ``` Closes rust-lang#67456. r? libs-api
