base: Add M5 flag for [[nodiscard]] attribute
This change adds the M5_NODISCARD keyword to allow use of the
[[nodiscard]] attribute with compilers that support C++17. Currently,
C++17 is not a requirement and therefore the M5_NODISCARD has not
effect and does not break compilation for older compilers.
