Various dtype improvements. (#5321)

* Various dtype improvements.

1) Add dtypes to the new data-based constructors: Variable.new_tensor and torch.autograd.variable.
2) In the python signatures, use Type instead of Dtype to match	the C++ signatures; the error messages still print as dtype.
3) Handle / add a better error message when a dtype is used when ATen was not compiled with that type (e.g. cuda types).
4) Move cuda_lazy_init to its own file.

A later commit will add support to the legacy constructors as well.

* Move implementation of lazy_init to cpp.

* Fix parsed_arg size.
