GFX control, no-tokio, no-async, dbus client refactor

- Working gfx modes <iGPU only, dGPU only, or hybrid>
- Add signal for gfx vendor change and make CLI wait for signal
- Add polling for led brightness to save to config
- Move daemon to zbus crate
- dbus client refactor
- Further dbus methods and updates
- Add basic notification user daemon and systemd service
