* feat(gnome): Use GDM on desktop
Restores GDM on desktop and implements GNOME autologin with GDM support. This allows
users to use screen locking. Omitted from Steam Deck as there isn't a seemingly clean
way to implement this for session switching. Will investigate in the future
* fix(gnome): Restore patched xorg-x11-server-Xwayland package for VRR

* fix: Stop caching flatpaks
These take up way too much space in images
* fix(flatpak-system-install): Require network connection
* fix(flatpak-system-install): Restart on failure
* fix(gnome): Add Silverblue flatpaks to install list
* fix(flatpak-system-install): Silence errors on package removal
A package may not be removed for a number of reasons, for example if someone were
to rebase from Kinoite to Bazzite GNOME, they wouldn't have the GNOME app suite
installed from Silverblue
* fix(deck): Don't try to install cached system flatpaks
