[libc++] Applied `[[nodiscard]]` to Language Support (partially) (#169611)

https://wg21.link/#support

`[[nodiscard]]` should be applied to functions where discarding the
return value is most likely a correctness issue.

- https://libcxx.llvm.org/CodingGuidelines.html#apply-nodiscard-where-relevant

The following was implemented in this patch:

- [x] `<compare>`
- [x] `<corotine>`
- [x] `<initializer_list>`
- [x] Integer comparisons
