fix: tick 动态化计算优化，减小中断执行时间对系统总体时间的影响，保证软件定时器的响应精度。

方案描述：
    1.周期软件定时器超时添加一个startTime字段，用于记录当前软件定时器的开始计时的时间，
    在定时器响应时，开始时间修改为上一次响应的结束时间(消除了中断执行时间对软件定时器
    的影响)。
    2. 在执行tick中断的过程当中，持有tick动态计算锁，保证在该过程中不会触发tick周期
    的计算，在tick中断结束时统一计算设置。 --- 提升tick中断的执行效率
    3. 在设置tick周期时，减掉tick中断执行的时间，减小周期动态化带来的时间误差
    4.新增LOSCFG_BASE_CORE_TICK_PER_SECOND_MINI配置宏，用于配置tick中断的最小响应精度
