COMP: Fix implicit copy constructor definition deprecation warnings

Fix implicit copy constructor definition deprecation warnings in
image/mesh file reader exception classes by using explicitly the
compiler-provided default implementation (together with the assignment
assignment and move semantics).

Fixes:
```
[CTest: warning matched]
 /Users/builder/externalModules/IO/ImageBase/include/itkImageFileReaderException.h:54:3:
 warning: definition of implicit copy constructor for 'ImageFileReaderException' is deprecated because it has a user-declared destructor [-Wdeprecated]
  ~ImageFileReaderException() noexcept override;
  ^
```

and
```
