[bling-gen-property-trees] Investigate non-latching/metrics ScrollingCoordinator behaviors

Project Member Reported by bokan@chromium.org, May 24 2018 
Ensure the following behaviors work correctly when the flag is enabled:

  Set cc::ScrollNode::overscroll_behavior with BlinkGenPropertyTrees
  Set cc::ScrollNode::snap_container_data with BlinkGenPropertyTrees
  Make scrollbar animations work with BlinkGenPropertyTrees
  Make position constraints work with BlinkGenPropertyTrees
