SurfaceFlinger: no app vsyncs during config switch

Do not dipatch vsync callbacks to applications during a config
switch as applications will get choreographer callbacks at uneven
times and will stuff the queue to surface flinger.

Test: test google/perf/jank/UIBench/UIBench-Trace:com.android.uibench.janktests.UiBenchJankTests#testClippedListView -v
