Optimize surface hierarchy
- Do not reset layer if layer doesn't change. JNI is expensive.
- Only assign child layers once if we have to do multiple passes.
- Fix issue where layouting the starting window caused the surface
to be resized, leading to a blocking SF transaction.
Test: go/wm-smoke
Test: adb logcat -b events | grep 319, inspect transition times.
