COMP: Use and move ITK_DISALLOW_COPY_AND_MOVE calls to public section

Use the `ITK_DISALLOW_COPY_AND_MOVE` macro in the `Watersheds` module to
enhance consistency across the toolkit when disallowing the copy
constructor and the assign operator.

Move the `ITK_DISALLOW_COPY_AND_MOVE` calls to public section following
the discussion in
https://discourse.itk.org/t/noncopyable
