Rollup merge of #130403 - eduardosm:stabilize-const_slice_from_raw_parts_mut, r=workingjubilee
Stabilize `const_slice_from_raw_parts_mut`
Stabilizes https://github.com/rust-lang/rust/issues/67456, since https://github.com/rust-lang/rust/issues/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 https://github.com/rust-lang/rust/issues/67456.
