testevdev: Verify most Wii devices against real hardware 

Some of the test data previously seen here was guessed from kernel
source code, and not all of it was correct. The following devices have
now been verified against `evemu-describe` output with Linux 6.3
(thanks to Jeremy Whiting for collecting this):

- basic Wiimote
    - buttons
    - 3-axis accelerometer
    - infra-red sensor for Sensor Bar location (precise aim)
- Motion Plus accessory (3-axis gyroscope)
- Nunchuck accessory (joystick, 2 buttons, second 3-axis accelerometer)
- Classic Controller accessory (a complete traditional gamepad)
