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
