Add support for the Keychron C2 V2 White (#987)

This adds support for the Keychron C2 V2 White. The RGB version is not
supported due to not owning an RGB C2 V2.

One thing this is missing is backlight controls, since the Keychron C2
V2 White uses LED Matrix (https://docs.qmk.fm/features/led_matrix).
While this is a feature in upstream QMK, and seems to be here, I'm not
sure if Vial explicitly supports LED Matrix in the GUI. LED Matrix is
not to be confused with RGB Matrix (the former being with single-color
LEDs and not RGB LEDs).
