feat: Add `bit_width` for unsigned `NonZero<T>`

- Tracking issue: rust-lang/rust#142326

This pull request adds a method to the unsigned `NonZero<T>` that return the minimum number of bits required to represent a value.

This can be achieved by using the `get` method and the methods added in rust-lang/rust#142328, but I think adding the `NonZero::bit_width` method is useful because it accomplishes the same thing a little more succinctly.
