ci: consider additional windows-run with Visual Studio

[GitMensch]

the GH Actions environment windows-2019 comes with Virtual Studio 2019 and vcpkg

A setup similar to this is actually running on Appveyor currently (and btw compiled latest GCOS adjustments, too); it may be useful to test complilation (and maybe running) with at least one non-gcc build (macos is likely clang, even if named gcc, but even then much more "like gcc")

That's the CI definition that would work in appveyor, giving an overview about steps to possibly add some day:

version: 3.2-dev.{build}-vs

image:
- Visual Studio 2019

configuration:
- Release
- Debug

platform:
- x86
- x64

clone_folder: C:\projects\gnucobol_vs

environment:
  WINFLEXBISON_VERSION: 2.5.24
  WINFLEXBISON_ARCHIVE: win_flex_bison-%WINFLEXBISON_VERSION%.zip

  VCPKGS: zlib:%PLATFORM%-windows liblzma:%PLATFORM%-windows mpir:%PLATFORM%-windows pdcurses:%PLATFORM%-windows berkeleydb:%PLATFORM%-windows libxml2:%PLATFORM%-windows cjson:%PLATFORM%-windows json-c:%PLATFORM%-windows

- cmd: >-
    set "OLDDIR=%CD%"
    echo Use vcpkg for pre-prerequisites &&   pushd c:\tools\vcpkg &&     git pull &&   .\bootstrap-vcpkg.bat &&   vcpkg integrate install &&   vcpkg install %VCPKGS% &&  vcpkg update &&  vcpkg upgrade %VCPKGS% --no-dry-run
    pushd %OLDDIR%

    echo Get flex/bison, include them in PATH
    if not exist "%WINFLEXBISON_ARCHIVE%" appveyor DownloadFile "https://github.com/lexxmark/winflexbison/releases/download/v%WINFLEXBISON_VERSION%/%WINFLEXBISON_ARCHIVE%"
    7z.exe x -y -owin_flex_bison\ "%WINFLEXBISON_ARCHIVE%" > nul
    set PATH=%CD%\win_flex_bison;%PATH%

cache:

- '%WINFLEXBISON_ARCHIVE%'

- c:\tools\vcpkg\installed\

- c:\tools\vcpkg\packages\

build_script:

- cmd: >-

    echo setup local configuration

    powershell -ExecutionPolicy ByPass -File build_windows\maketarstamp.ps1 > tarstamp.h

    echo doing the actual build - bison + flex
    call build_windows\makebisonflex.cmd || appveyor AddMessage "bisonflex returned with %errorlevel%" -Category Warning

    echo doing the actual build - GnuCOBOL
    msbuild "C:\projects\gnucobol_vs\build_windows\2019\GnuCOBOL.sln" /m /verbosity:minimal /logger:"C:\Program Files\AppVeyor\BuildAgent\Appveyor.MSBuildLogger.dll"


    echo exporting dependencies
    vcpkg.exe export %VCPKGS% --raw
    move C:\Tools\vcpkg\vcpkg-export-* .\vcpkg-export
    set "VCPKG_EXPORT_DIR=%CD%\vcpkg-export"

    echo create binary dist package
    call build_windows\makedist.cmd %CONFIGURATION%

    echo wrap up dependencies for separate download
    7z.exe a -r -mx=9 "%DEP_ARCHIVE%" vcpkg-export

test: off

artifacts:

- path: build_windows\GnuCOBOL*.7z
  name: Package for VS

- path: '%DEP_ARCHIVE%'
  name: Dependencies

The only testing done here is the build of the dump module, there are some test options available (non used in appveyor so far)
