Updates to restore to a functional state

Changes:
- Add setenv of QT_QUICK_CONTROLS_STYLE and setting of the
  frameless window hint to match the previous behavior before the
  removal of the previous application framework.
- Use the new VehicleSignals API from libqtappfw to replace the
  previous signal-composer usage.
- Update the use of the Navigation API from libqtappfw for its
  rework to use VIS signals instead of the previous signal-composer
  usage.
- The default unit for the vehicle speed has been switched to
  kilometers with switching driven by the appropriate VSS schema
  value.
