evdev: Factor out the xkbcommon code from the wayland client backend

The wayland client code has support for translating raw linux input device key codes coming from the wayland compositor into key symbols thanks to libxkbcommon. A backend directly listening to linux input devices (called evdev, just like the Xorg one) could use exactly the same code for the translation, so abstract it a bit in a separate file.
