Ember ES Class Todos

• Update constructor to receive arguments directly
  • Implemented in this PR, just needs review and merge
  • Probably could be simplified in Ember 3, we can remove multi-object create
• Update concatenated and merged properties in RFC
  • Concatenated and merged properties will not be able to work the way they used to.
  • No way to know the value of a field before an instance is created
  • Parent class constructor finishes before child constructor, so no way to get value in makeCtor base constructor
• Fix native getters/setters (make mandatory setter aware of them)
  • applyMixin , watchKey, and defineProperty erase native getters and setters
