Fix DDS and winreg missing in Python plugins

- Stage DDS/ package from source directly to plugins/data/DDS/ in
  build-inner.sh (cmake MO2_STAGE_PYTHON_PLUGIN_PAYLOAD is OFF by
  default so the cmake-sourced path was silently skipped)
- Stage winreg.py from libs/ directly as well (same root cause)
- Guard `import winreg` in gog_utils.py with try/except ImportError
  and early-exit to Heroic GOG path if the shim is unavailable
