[DESK] Implement pCDevSettings_GetDeviceInstanceId properly

- CM_Locate_DevNodeW expects a Device Instance ID as second argument,
  so it cannot be used for converting a Hardware ID.
- Use SetupAPI functions here instead, as documented in:
  https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-enumdisplaydevicesw
- Now our desk.cpl passes correct identifier to CPL extensions,
  such as deskadp and deskmon, so clicking on "Properties" in the
  advanced display properties now works in Windows XP.
- Also fix copypasta in DisplayAdvancedSettings that affected applet
  built with MSVC - deskadp extension was loaded twice.
- Also fix magic flag value for EDD_GET_DEVICE_INTERFACE_NAME.
