seat-native: Add support for tablet-mode-switch being hot-unplugged

Browse Source 
Add support for the (mostly theoretical) case of an input-device
offering tablet-mode-switch functionality being unplugged.

This makes the has_tablet_switch handling identical to the has_touchscreen
handling, leading to more consistent code.
