[libc++][numeric][NFC] Cleanup *Saturation arithmetic* tests (#101826)
This simplifies the tests a little bit: Fixed -> TODO(LLVM20): remove [[maybe_unused]] and `{}` scope since all supported compilers support "Placeholder variables with no name" *IMPORTANT: Requires Apple Clang with [P2169R4: A nice placeholder with no name](https://wg21.link/P2169R4)* --------- Co-authored-by: Hristo Hristov <[email protected]>
