Fix PointerHandler constructors and destructors

- Constructors should take QQuickItem* not QObject* to be symmetric
  with the parentItem() accessor (and other code) which assumes its type
- Use header initialization everywhere possible
- Reorder variables to minimize padding (somewhat)
- Remove empty destructor bodies (the compiler can write them)
- Remove override and virtual from destructors in accordance with
  https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Rh-override
