GitHub Actions: make console output visible on Windows

[TheMostDiligent]

To avoid future problems with tests on CI, it is important for us to enable console output on CI.
@MikhailGorobets Experiment with a separate repository: create a simple Win32 application by following Diligent Win32 main (you do not need Direct3D at all), print some messages from this app and start it from batch script on CI - figure out how to make output visible.
