feat: L0-L1 支持Trace
1.【需求描述】
L0~L1 支持Trace，提供两种工作模式：在线模式、离线缓存模式， 用于按时间线追踪系统事件，如任务切换、中断、ipc等。
2.【方案描述】
L0:
(1).在内核模块预置静态代码桩
(2).触发桩后，收集系统上下文信息
(3).离线模式则写入内存，用户可通过dump导出；
(4).在线模式通过pipeline对接IDE进行可视化解析和展示；
L1:
新增trace字符设备，位于"/dev/trace",通过对设备节点的read\write\ioctl，实现用户态trace；
BREAKING CHANGE:
1.新增一系列trace的对外API，位于los_trace.h中.
LOS_TRACE_EASY简易插桩
LOS_TRACE标准插桩
LOS_TraceInit配置Trace缓冲区的地址和大小
LOS_TraceStart开启事件记录
LOS_TraceStop停止事件记录
LOS_TraceRecordDump输出Trace缓冲区数据
LOS_TraceRecordGet获取Trace缓冲区的首地址
LOS_TraceReset清除Trace缓冲区中的事件
LOS_TraceEventMaskSet设置事件掩码，仅记录某些模块的事件
LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数
