Auto merge of #86433 - paolobarbolini:string-overlapping, r=m-ou-se
Use `copy_nonoverlapping` to copy `bytes` in `String::insert_bytes` The second copy could be made using `ptr::copy_nonoverlapping` instead of `ptr::copy`, since aliasing won't allow `self` and `bytes` to overlap. LLVM even seems to recognize this, [replacing the second `memmove` with a `memcopy`](https://rust.godbolt.org/z/Yoaa6rrGn), so this makes it so it's always applied.
