WinForms tests are not building in VMR

[NikolaMilosavljevic]

The build is failing with the following issue (dotnet/sdk#44843 (comment)):

The command "
      call "D:\a\_work\1\vmr\src\winforms\eng\init-vs-env.cmd" 
      
       cmake -G "Visual Studio 17 2022" -A Win32 -B "D:\a\_work\1\vmr\src\winforms\artifacts\obj\NativeTests\x86\Release" -S "D:\a\_work\1\vmr\src\winforms\src\System.Windows.Forms\tests\InteropTests\NativeTests" -DCMAKE_INSTALL_PREFIX=D:\a\_work\1\vmr\src\winforms\artifacts\bin\NativeTests\x86\Release --log-level=WARNING
      " exited with code 1.

I've opted out of building tests in this repo with dotnet/sdk#44843
