[libc] Make static_assert available even if NDEBUG is set (#99742)
This addresses an issue introduced in #98826 where static_assert was
made defined only when NDEBUG is not set which is different from all
other C libraries and breaks any code that uses static_assert and
doesn't guard it with NDEBUG.
