This reverts commit 0e47e07b.

Move neofetch and btop to desktop+ximper tag. Add cascadia-code font, extension-manager, switcheroo-control to default packages.

add etersoft groups etersoft/virt-machines etersoft/virt-manager etersoft/gnome-boxes etersoft/virtualbox etersoft/00_office etersoft/libreoffice-still etersoft/libreoffice-latest etersoft/01_games and others

Since lib already comes to all desktops, adding this utility does
not add weight to images. There will be more and more desktops on
wayland, so it will be useful.

No other build targets are planned.

kde5-falkon is not available (since falkon >= 24.08.2-alt1)
