[CUDA][HIP] Change default lang std to c++14 Currently clang and nvcc use c++14 as default std for C++. gcc 11 even uses c++17 as default std for C++. However, clang uses c++98 as default std for CUDA/HIP. As c++14 has been well adopted and became default for clang, it seems reasonable to use c++14 as default std for CUDA/HIP.
