PerformanceHintManager.Session is in java, so add JNI and a HintSessionWrapper class in HardwareRenderer. Then pass the two calls as two std::functions into DrawFrameTask. Note Session is created per HardwareRenderer, not global (per RenderThread). Session includes UI thread, render thread, and the thread pool. Desired duration is from the intended start duration to the frame deadline. Add an actual frame start time to compute Add system properties: debug.hwui.use_hint_manager to enable PerformanceHintManager debug.hwui.target_cpu_time_percent to control percentage of frame time to be used for target cpu duration. Test: Manual test that there are no crashes and values make sense. Bug: 158791282 Change-Id: I83f25433c10daa20033803fb7c4ae45eab34f1d3
