Run the Windows Craft jobs automatically when previous stages succeeded

This aligns the Windows Craft jobs with the Android Craft jobs. This also fixes the problem that the sign_appx_qt515 job runs (and fails) even if the craft_windows_qt515_x86_64 job failed (because, by default, failing manual jobs do not block dependent jobs).

The other commit removes properties that are not shared by all derived jobs from the base job. We use the same approach for the Android jobs.
