Add type hints to python for class constructors

* We enforce default and copy constructors where possible, this isn't very
  pythonic but we can't use copy.deepcopy on our types.
* The structs that have specialised constructors e.g. FloatVector or Subresource
  also have those documented though we have no way to enforce it.
