ozone: evdev: Factor keyboard into KeyboardEvdev

This object is responsible for combining all attached keyboards into one
logical keyboard, applying modifiers & implementing key repeat. Key
repeat is not done yet.

We need this so we can also dispatch keypresses from gestures devices
(e.g. Logitech K400).

Why not use std::bitset?
