[vcpkg baseline][dcmtk] Remove the leading spaces of pc file

[Cheney-W]

Fixed CI pipeline issue:

dcmtk:x86-windows
dcmtk:x64-windows
dcmtk:x64-windows-static
dcmtk:x64-windows-static-md

CMake Error at scripts/cmake/vcpkg_fixup_pkgconfig.cmake:141 (message):
  D:/downloads/tools/msys2/6f3fa1a12ef85a6f/mingw32/bin/pkg-config.exe
  --exists dcmtk failed with error code: 1
      ENV{PKG_CONFIG_PATH}: "D:/packages/dcmtk_x64-windows-static/lib/pkgconfig;D:/packages/dcmtk_x64-windows-static/share/pkgconfig;D:/installed/x64-windows-static/lib/pkgconfig;D:/installed/x64-windows-static/share/pkgconfig"
      output: Package dcmtk was not found in the pkg-config search path.
  Perhaps you should add the directory containing `dcmtk.pc' to the PKG_CONFIG_PATH environment variable
  Package 'dcmtk', required by 'virtual:world', not found

This issue occurred after the merge of PR #31924. When I tried using the older version of pkg-config, the problem disappeared. I checked the relevant files of dcmtk, and there have been no recent changes to them.

Remove the leading spaces of pc file could fix this issue.

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

This is simply ignoring the problem instead of fixing it. You need to figure out why pkgconf fails. You need to manually run the command an enable verbose output.

Any progress?

I have tried the options provided by pkg-config.exe, but they didn't give me more detailed error information.
However, I noticed that there is a space at the beginning of each line in the dcmtk.pc file. If I remove the leading space from the lines mentioned below, it fixes the error.

 Name: DCMTK
 Description: DICOM Toolkit (DCMTK)
 URL: https://dcmtk.org
 Version: 3.6.7

These spaces are from the pc.in file provided by the upstream. In order to maintain consistent formatting, I have removed the leading spaces from each line.
