Add "Keyboard Setup Assistant" to execute the desktop when the keyboard is inserted or on the Live CD, so that all regional keyboards can benefit

There is a "Keyboard setup assistant" setting in the new user settings for the first startup on the Mac, or when a new keyboard is inserted. This function can solve the problem of different keyboard layouts in different countries. It should be implemented on this OS solve
I just want to add "Options for the arrangement of the control keys for the PC" to the keyboard layout ,Because the PC’s Super (Command) key is opposite to the Alt (Option) key and the Mac’s keyboard configuration.

Layout | Left 1 | Left 2 | Left 3 | Left 4 | Space | Right 4 | Right 3 | Right 2 | Right 1 |
--- | --- | --- | --- |--- | ---| ---: | ---: | ---:| ---: |
**PC :** | Null | Ctrl (Control) | _**Super (Command)**_ | _**Alt (Option)**_ | Space | _**Alt (Option)**_ | _**Super (Command)**_ | Menu | Ctrl (Control) |
**Mac:** | Fn | Control | _**Option (Alt)**_ | _**Super (Command)**_ | Space | _**Command (Super)**_ | _**Option (Alt)**_ | Null | Control |
