More IO fixups for utf-8 support on Windows

This provides utf-8 support for a few more IO classes on Windows.

The classes that have been changed are:

• vtkTeclplotReader
• vtkTIFFReader and vtkTIFFWriter
• vtkNIFTIImageReader and vtkNIFTIImageWriter
• vtkDirectory

Since vtkDirectory is used internally by several other classes, the following will also see improved utf-8 support:

• PIOAdaptor
• vtkOpenFOAMReader and vtkPOpenFOAMReader
• vtkRTXMLPolyDataReader
• vtkDICOMImageReader

Closes: #17779 (closed)

Errors:

• commit 79d3f3ba is not allowed because the following files are not formatted according to the 'clang-format' check: IO/Image/vtkNIFTIImageReader.cxx, IO/Image/vtkNIFTIImageWriter.cxx. Post a comment ending in the line Do: reformat to rewrite the MR source branch automatically.

Please rewrite commits to fix the errors listed above (adding fixup commits will not resolve the errors) and force-push the branch again to update the merge request.

@ben.boeckel Can you review? This uses KWSys to get utf-8 filenames to work in a few classes on Windows.

Thanks. AFAIK this covers the remaining utf-8 stuff that's within our control.
