This was already only enabled in debug_assertions builds. Generally, it seems
like most use cases that would use this could also use the -Zself-profile flag
which also tracks cache hits (in all builds), and so the extra cfg's and such
are not really necessary.

This is largely just a small cleanup though, which primarily is intended to make
other changes easier by avoiding the need to deal with this field.

Add #[must_use] to as_type conversions

Clippy missed these:

```rust
alloc::string::String   fn as_mut_str(&mut self) -> &mut str;
core::mem::NonNull<T>   unsafe fn as_uninit_mut<'a>(&mut self) -> &'a MaybeUninit<T>;
str                     unsafe fn as_bytes_mut(&mut self) -> &mut [u8];
str                     fn as_mut_ptr(&mut self) -> *mut u8;
```

Add #[must_use] to len and is_empty

Add #[must_use] to non-mutating verb methods

These are methods that could be misconstrued to mutate their input, similar to rust-lang#89694. I gave each one a different custom message.

I wrote that `upgrade` and `downgrade` don't modify the input pointers. Logically they don't, but technically they do...

Add #[must_use] to is_condition tests

I threw in `std::path::Path::has_root` for funsies.

A continuation of rust-lang#89718.

fix minor spelling error in Poll::ready docs

Fixes minor spelling error in the proposed `Poll::ready` docs. Not that my opinion matters, but +1 on the original PR (rust-lang#89651), it reads much nicer to me than the `ready!` macro.
