[atomic]添加arm与risc-v下的常用原子操作函数 (#7053)
* Update Kconfig
* Update trap_gcc.S
* Update bsp/hifive1/drivers/SConscript

Co-authored-by: Man, Jianting (Meco) <920369182@qq.com>
* Update SConscript
* [atomic]提交一份arm与risc-v架构下的常用原子操作函数
* 修改变量类型
* 更新rtatomic.h与atomic_port.c
* 更新rt-thread\libcpu\arm\common\atomic_port.c
* 更新include/rtatomic.h与libcpu/arm/common/SConscript
* 更新include/rtatomic.h
* 修正格式与Kconfig
* 修正格式与文件结构

* 规范文件格式与文件重命名
* 添加测试用例与CI
* 添加函数声明
* 修改virt64/SConscript 添加atomic_riscv.c
  * 1.规范代码风格
  * 2.添加RISC-V64原子指令支持 解决在RV64下编译器将32-bit运算结果扩展为64-bit 导致判断错误
* 添加C11标准库原子操作测试
