LiteOS2021 e748fdbe57 feat: L0~L1 支持Lms 
1.【需求描述】：
   支持内核态和用户态堆内存非法访问检测，包括：越界访问、double free、释放后使用；支持libc常用高频函数内存检测；支持安全函数内存检测；读写检测可配可裁剪。
2.【方案描述】：
   L0 ~ L1:
   (1).影子内存映射与标记
   (2).编译器使能-fsanitize=kernel-address 自动插桩检测点
   (3).实时校验影子内存的合法性；
   (4).错误访问打印回溯栈

BREAKING CHANGE: 新增支持API:

LOS_LmsCheckPoolAdd使能检测指定内存池
LOS_LmsCheckPoolDel不检测指定内存池
LOS_LmsAddrProtect为指定内存段上锁，不允许访问
LOS_LmsAddrDisableProtect去能指定内存段的访问保护

arvinzzz 33d0c1bd0b refactor: 内核目录结构整理 
1. 原kernel/common目录下属于内核拓展组件，统一移入kernel/extend管理
2. Kconfig分层，各模块自己的配置放到自己目录下管理
3. 原platform下不属于平台的公共代码抽到kernel/common下，只留板级链接脚本和一些编译脚本指向device目录下触发平台相关的编译
4. 对外公共头文件统一抽到对外include路径
5. 废弃宏，头文件清理
