Automatically group sub-commands ##newshell (#17663)
* Add GROUP RCmdDesc type and fix where the args_str is shown
* Adjust color of `[?]`
* Differentiate between cmd<?> and cmd[?]
<?> when cmd is not valid by itself
[?] when cmd is valid but there are also other sub-commands available
* Fix usage for commands like `w` that are both commands and groups
* Do not automatically switch to detail=2 for leaf commands
* Fix test due to change in `?`/`??` behaviour
