dcea1b90e7 arch_atomic: only support atomic_xx and atomic64_xx function
Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.

2275138dcf arch_atomic : Introduce CONFIG_LIBC_ARCH_ATOMIC
Some armv7-m-based SoCs do not work with atomic instructions,
even though armv7-m supports them.

To avoid using atomic instructions generated by gcc,
CONFIG_LIBC_ARCH_ATOMIC is newly introduced with which
arch_atomic.c is linked explicitly.

However, the function names need to be changed to avoid
build errors, since the functions described in stdatomic.h
are gcc built-in and inlined when the code is compiled.

About libcxx with CONFIG_LIBC_ARCH_ATOMIC, it still
does not work. It is also needed to call nx_atomic_ ver
instead of __atomic ver in
libcxx/include/__atomic/cxx_atomic_lmpl.h.

Summary:
