nuttx/atomic: use toolchain builtin atomic function
The reason for using builtin atomic is that in C++, when include <atomic> in <nuttx/atomic.h> easily conflicts with third-party function libraries. We wanted to completely separate the implementation of <nuttx/atomic.h>. There are two points: 1. use builtin function directly. 2. Without the standard library implementation, need implement "atomic_fetch_xxx", leading conflicts with the standard library used by third-party programs, introducing redefinition issues and requiring name changes.
