Implement Display Layer Stats V0.1

Try to collect data for analyzing how many display controller layers we
need and what we use them for. This change will collect additional data
from per frame point of view.

Test: adb shell dumpsys SurfaceFlinger --enable-layer-stats
Test: adb shell dumpsys SurfaceFlinger --disable-layer-stats
Test: adb shell dumpsys SurfaceFlinger --clear-layer-stats
Test: adb shell dumpsys SurfaceFlinger --dump-layer-stats
