Subject: [PATCH 1/2] Add TTY switching support for Chromebook keyboards

Enable Ctrl+Alt+F1-F8 TTY switching for both keyboard modes:
- Inverted mode: F-keys map directly to TTY switches
- Non-inverted mode: Chrome keys (back/forward/refresh/etc) map to TTY switches

This allows proper virtual console access on Chromebooks running Linux,
which is essential for troubleshooting, recovery, and server management.

Subject: [PATCH 2/2] 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
