DEV 21.01.24

1. 本次更新合并了40+个commit
2. 新增：适配骁龙888和Linux 5.4引入的uclamp
3. 新增：仅允许后台与UX相关的线程运行在大核，减少大核唤醒
4. 新增：固定全面屏手势动画相关的线程到大核且不被抢占，减少掉帧
5. 新增：动态控制UI渲染管线相关线程到大核，减少掉帧
6. 新增：优化基于Unity游戏线程放置的合理性，减少迷之掉帧
7. 新增：CPU频点模糊匹配
8. 新增：识别zygote，修复偏慢的APP冷启动
9. 新增：重构动态Affinity，改善线程调度参数设置生命周期完整性
10. 改进：恢复WALT EAS负载预测，修复选频过于保守
11. 改进：加快HeavyLoad检测频率到20hz
12. 改进：卡顿和均衡模式小核最低频使用尽可能低的值
13. 修复：goodix和屏幕指纹动画线程被固定到小核，修复MIUI屏幕指纹解锁停顿太久
14. 修复：SfAnalysis在MIUI 12.5初始化失败
15. 修复：关闭高通perfd时拉高的DDR频率没有恢复导致空载高耗电
16. 修复：sigwait遗漏信号导致状态卡在Sflag
17. 修复：一个罕见的崩溃bug
