RJ Trujillo eeb93f9700 feat: Overhaul images
These changes effectively make the structure similar to bluefin.

bazzite now serves as a base for desktop configurations and now
bazzite-deck has been introduced to add changes specific to the
Steam Deck and Steam Deck-alike configurations. Also:

- Introduce images built from main for non-Nvidia systems
- Consolidate structure (remove duplicates, merge Containerfiles)
