  [CUDA][HIP] Add a __device__ version of std::__glibcxx_assert_fail() (#136133)

libstdc++ 15 uses the non-constexpr function
std::__glibcxx_assert_fail() to trigger compilation errors when the
__glibcxx_assert(cond) macro is used in a constantly evaluated context.

Compilation fails when using code from the libstdc++ (such as
std::array) on device code, since these assertions invoke a
non-constexpr host function from device code.

This patch proposes a cuda wrapper header "bits/c++config.h" which adds
a __device__ version of std::__glibcxx_assert_fail().
