We have the option of const-stabilizing this now that #57349 has stabilized.

Team member @dtolnay has proposed to merge this. The next step is review by the rest of the tagged team members:

No concerns currently listed.

Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

See this document for info about what commands tagged team members can give me.

 Stabilize 5 `const_mut_refs`-dependent API

Since `const_mut_refs` and `const_refs_to_cell` have been stabilized, we now may create mutable references inside our library API. Thus we now stabilize the `const fn` version of these public library APIs which required such in their implementation:
- const `NonNull::as_mut` rust-lang#91822 (comment)
- const `slice::{first,last}_mut`: rust-lang#83570 (comment)
- const `str::as_{mut_ptr,bytes_mut}`: rust-lang#130086 (comment)
- const `str::from_utf8_unchecked_mut`: rust-lang#91005 (comment)
- const `UnsafeCell::get_mut`: rust-lang#88836 (comment)
