Fix C++17 constexpr storage deprecation warnings
This change introduces the symbol ABSL_INTERNAL_NEED_REDUNDANT_CONSTEXPR_DECL to guard redundant declarations of static constexpr data members that are needed prior to C++17. This change also introduces the symbol ABSL_INTERNAL_CPLUSPLUS_LANG, which is supposed to be set to the same value as __cplusplus, except it uses _MSVC_LANG on MSVC so that the value is correct on MSVC. Neither of these new symbols should be used outside of Abseil. Fixes #1191 PiperOrigin-RevId: 453923908 Change-Id: I1316c52c19fa0c168b93cced0c817e4cb7c9c862
