Auto merge of #124498 - tgross35:stabilize-non_null_convenience, r=jhpratt

Stabilize `non_null_convenience` Fully stabilize the following API, including const where applicable: ```rust impl NonNull { pub const unsafe fn offset(self, count: isize) -> Self; pub const unsafe fn add(self, count: usize) -> Self; pub const unsafe fn sub(self, count: usize) -> Self; pub const unsafe fn offset_from(self, origin: NonNull) -> isize; pub const unsafe fn read(self) -> T; pub unsafe fn read_volatile(self) -> T; pub const unsafe fn read_unaligned(self) -> T; pub unsafe fn write_volatile(self, val: T); pub unsafe fn replace(self, src: T) -> T; } impl<T: ?Sized> NonNull { pub const unsafe fn byte_offset(self, count: isize) -> Self; pub const unsafe fn byte_add(self, count: usize) -> Self; pub const unsafe fn byte_sub(self, count: usize) -> Self; pub const unsafe fn byte_offset_from<U: ?Sized>(self, origin: NonNull) -> isize; pub unsafe fn drop_in_place(self); } ``` Stabilize the following without const: ```rust impl NonNull { // const under `const_intrinsic_copy` pub const unsafe fn copy_to(self, dest: NonNull, count: usize); pub const unsafe fn copy_to_nonoverlapping(self, dest: NonNull, count: usize); pub const unsafe fn copy_from(self, src: NonNull, count: usize); pub const unsafe fn copy_from_nonoverlapping(self, src: NonNull, count: usize); // const under `const_ptr_write` pub const unsafe fn write(self, val: T); pub const unsafe fn write_bytes(self, val: u8, count: usize); pub const unsafe fn write_unaligned(self, val: T); // const under `const_swap` pub const unsafe fn swap(self, with: NonNull); // const under `const_align_offset` pub const fn align_offset(self, align: usize) -> usize; // const under `const_pointer_is_aligned` pub const fn is_aligned(self) -> bool; } ``` Left the following unstable: ```rust impl NonNull { // moved gate to `ptr_sub_ptr` pub const unsafe fn sub_ptr(self, subtracted: NonNull) -> usize; } impl <T: ?Sized> NonNull { // moved gate to `pointer_is_aligned_to` pub const fn is_aligned_to(self, align: usize) -> bool; } ```Fixes: #117691
