LegacyJoystickDriver implements the legacy IJoystickDriver interface (GameWindow.Joysticks) in terms of the new IJoystickDriver2 interface (OpenTK.Input.Joystick). This removes a large chunk of code from each platform backend, as they no longer need to implement IJoystickDriver themselves. Additionally, it adds support for device hot plugging which was previously missing.
