DEV 21.05.23

1. 本次更新合并了20+个commit
2. 新增：SfAnalysis可完整监控帧提交完整流程，内容刷新率切换延迟200ms->110ms
3. 新增：变时长sflag和sfboot，可在发生卡顿的帧渲染结束后提前结束
4. 新增：显式触摸状态hint，方便对触摸各个阶段定制对应action
5. 改进：卡顿模式改用超低主频方案，充分发挥变时长sflag和sfboot特性
6. 改进：费电模式改用高主频方案，不同设备stune支持差异较大例如移植的EAS和PELT EAS
7. 改进：bootloop recuser统一到在postfs阶段放置标志位，正常开机后模块不再显示为禁用
8. 改进：动态帧率切换改为同步调用，解决异步+固定等待时长导致的时序问题
9. 改进：降低过渡动画对应动作性能拉升强度，延长持续时间，配合Sfboost兼顾流畅度和功耗
10. 改进：webview线程放置，H5页面滑动和公众号文章浏览流畅度更好
11. 改进：配合kworker执行时序，CPU主频设置延时0.6ms->0.2ms
12. 改进：减少任务放置执行数量，任务放置延时0.6ms->0.4ms
13. 改进：小重构TaskClassfier代码实现
