add "Resolution : Best for Retina display" for linux guest

Hello, for windows machines, there is the option "Resolution : Best for Retina display" in hardware settings -> graphics settings, but Linux does not.
I think it's very useful.
Maybe it can be implemented for a certain desktop environment, such as KDE or gnome. Or for some popular distribution, such as Kali, Ubuntu.
I think the implementation of this function is relatively simple. For Gnome in Ubuntu, you only need to execute one command. Other distributions may not be complicated
