Enhance 14900k configuration with streaming display support and virtual EDID generation

- Added a new `streaming-display.nix` module to configure a headless 4K virtual output for Sunshine and Moonlight.
- Introduced a Python script `generate-virtual-edid.py` to create a virtual display EDID with 4K capabilities.
- Updated `configuration.nix` to integrate the new streaming display module and enable related services.
- Modified `displays.nix` to accommodate the new streaming display settings and ensure compatibility with existing GPU passthrough configurations.
