nuttx/atomic: for builtin atomic, a wrapper is used to unify the names.
1. for tasking, map __c11_atomic_xxx as tasking_atomic_xxx 2. for msvc, map _Interlocked_xxx as msvc_atomic_xxx 3. if no special map, use gcc/clang as default as they are most widely used. Signed-off-by: zhangyu117 <zhangyu117@xiaomi.com>
