Implement Display Layer Stats
Try to collect data for analyzing how many display controller layers we
need and what we use them for. Also part of a bug fixing for potential
memory leak of existing layer tracing work of winscope.
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
