[libcpu/arm64] add C11 atomic ticket spinlock (#8882)
* [libcpu/arm64] add C11 atomic ticket spinlock

Replace the former implementation of flag-based spinlock which is unfair

Besides, C11 atomic implementation is more readable (it's C anyway),
and maintainable. Cause toolchain can use their builtin optimization and
tune for different micro-architectures. For example armv8.5 introduces a
better instruction. The compiler can help with that when it knows your
target platform in support of it.
