libstdc++: Add noexcept to __replacement_assert [PR101429]

This results in slightly smaller code when assertions are enabled when
either using Clang (because it adds code to call std::terminate when
potentially-throwing functions are called in a noexcept function) or a
freestanding or non-verbose build (because it doesn't use printf).
