Adds code to track whether SurfaceFlinger has sent two frames to HWC in the same vsync window. This can occur if one frame is delayed so far it slips into the next window or just if one frame takes an abnormal amount of time. If this occurs, it shows up as FrameMissed in systrace. Also adds a property debug.sf.drop_missed_frames which, if set, tells SurfaceFlinger to skip sending a frame to HWC (i.e., calling prepare/set) when we detect this condition, which can help prevent backpressure from the HWC implementation.
