Dispatch vsync when receiving vsync timeout to handle vsync loss.

Currently we do not have a mechanism to guarantee the arrival of the vsync signal. The vsync signal loss may occur when the renderNodeAnimator is running. The render thread took a long time to perform drawing without time to read the pipe, and the pipe was filled with other signals like configChanged, causing surfaceflinger to miss a vsync signal.
If a vsync lost, causing DisplayEventDispatcher::mWaitingForVsync to be true, resulting in DisplayEventDispatcher::scheduleVsync can no longer schedule another vsync. So we need to dispatch vsync when receiving vsync timeout.
