feat(keyboard): dynamically generate TTY switching mappings

- Add get_tty_switching() function to generate mappings based on physmap
- Remove hardcoded key mappings (brightnessdown, brightnessup, mute)
- Support all top row keys dynamically (10-12 keys vs previous 8)
- Ensure compatibility with all Chromebook vivaldi keyboard layouts
- Works for both inverted and non-inverted keyboard modes
