Added debugger

- disabled already selected dxvk/runner re-selection
- fixed `Voice.current` output
- made `Debug` and `DebugThread` classes
- fixed `winecfg` usage during DXVK installation
- `bash` usage was changed to the `./`
- added voice update state identification
- fixed shaders usage in game launching script
- added debugging to the `[launchder]/logs` folder
