STYLE: Improve the ivar printing in PrintSelf method

jhlegarreta · dzenanz · commit 33c7d9ebacaa · 2022-08-24T09:55:44.000-04:00
Improve the ivar printing in `PrintSelf` method:
- Use the `itkPrintSelfObjectMacro` macro to avoid boilerplate code when
  printing smart pointers/objects that can be null pointers.
- Remove printing ivars of an ivar: printing the ivar will print it
  the values of its ivars.
