COMP: Install GDCM DebugDevel component in libitk-devel package

On Windows, the GDCM-bundled jpeg libraries (gdcmjpeg8/12/16) install
their static .lib archives under the "DebugDevel" CMake component, not
"Development". ITKTargets.cmake references these .lib files, so without
this component the downstream find_package(ITK) test fails:

  CMake Error at ITKTargets.cmake:2172:
    The imported target "ITK::gdcmjpeg8" references the file
      "%PREFIX%/Library/lib/itkgdcmjpeg8-6.0.lib"
    but this file does not exist.

Add DebugDevel to both install scripts for cross-platform consistency.
On Linux/macOS the component produces no output (gdcmjpeg static archives
are not exported there), so it is a safe no-op on those platforms.
