Reduce number of binders from SurfaceFlinger for ADPF

Currently, SF is using the wrong vsync value when calculating the
target for ADPF, causing it to send a binder every frame instead of
every vsync change. This patch fixes that to reduce the binder
frequency from SF, and also adds a debug option to disable reportActual
to reduce the amount of binders even more in certain cases.
