surfaceflinger: Track the last surfaceview frame for latency dumps
When measuring GL latency with dumpsys, it's possible to hit a
race condition if the hardware is fast enough to complete rendering
the test cycle before the latency dump is requested, since it only
matches the latency for live layers (unless it's an animation. See
change I8bded1ea08a4cddefef0aa955401052bb9107c90)
So always save a reference to the last rendered SurfaceView frame,
and dump its values if there isn't an active one.
