fix: 修复重复执行内存用例导致系统卡死问题
...
背景：重复执行内存测试用例约几百次，系统大概率出现卡死现象，经分析知，系统卡在
内存spinlock锁中，CPU1在获取内存spinlock锁后打印异常信息，此时循环buffer满了，
CPU0此时进入异常且尝试拿取内存spinlock锁，两个核都处于锁中断锁任务状态，CPU1
写事件触发调度打印输出失败，进而在write接口中死循环无法退出，导致两个核都卡住。
方案：在write接口中增加一个判断条件：当前核处于锁任务状态且循环buffer满了时候，
直接退出循环，丢弃打印信息（持有spinlock锁后一般禁止输出打印信息）。

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
