异常类型：IdleHandlerLagTracer 存在 fd 泄漏

手机型号：任意

手机系统版本：任意

matrix版本：2.0.8、2.1.0

gradle版本：任意

问题描述：App 进入 ActivityA 后，会调用 Tracer.onStartTrace 开启监控，退出 ActivityA 会调用 Tracer.onCloseTrace。StartTrace 后 IdleHandlerLagTracer 会初始化 idleHandlerLagHandlerThread，关键问题是 idleHandlerLagHandlerThread 在 onDead 没有调用 quit，HandlerThread 的线程将继续运行，导致 fd 泄漏。

Screenshot

这里贴一下线上使用 koom 收集到 fd 泄漏的情况，IdleHandlerLagThread 泄漏高达 92 次，建议尽快修复
