generate *.vcxproj file lists with dmake

[firewave]

cli.vcxproj and testrunner.vcxproj are changed completely since the newlines were wrong (CR instead of CRLF). We need a proper .gitattributes file which enforces those. To view those changes you need to enable the Hide whitespace option in the diff viewer (accessible via the "gear" icon).

The added Label attribute is allowed - it is simply not used by Visual Studio in those files. It does allow use to define marker and the file lists in question so we can rewrite them.

I have no added writing of the *.vcxproj.filters yet but that is simply for grouping in the IDE and has no effect on the builds. Will add that in a later PR.

The dmake.vcxproj is also lacking x64 build configurations and is not aligned with the settings of our other projects - will do that in a different PR but that is not really necessary since it is not used in production/CI or being shipped. It is also not build by default. I mainly added it so I can debug it on Windows as well as pulling it out of obscurity (I wasn't even aware there was a Visual Studio project for it until a few weeks ago).

With the files normalized we no longer need the hack in the CI and this PR will now properly show all the changes without adjusting the viewer options.

I think your approach is reasonable 👍

To read the existing vcxproj file and just replace the file lists.

Anything left to do to get this merged?
