cts case
com.android.server.cts.GraphicsStatsValidationTest#testDaveyDrawFrame in
modue CtsIncidentHostTestCases failed
This cts case design 20 frames, every 4 frames include 700ms frame and
150ms frame
When activity launched, first 3 frames need allocate buffer during
dequeue buffer, bug some low-end platform took too long (>6ms), so
it will skip the fourth frame(150ms) and post a new draw callback that will cause cts failed
