platform/x86/tuxedo: Add virtual LampArray for TUXEDO NB04 devices
The TUXEDO Sirius 16 Gen1 and TUXEDO Sirius 16 Gen2 devices have a per-key
controllable RGB keyboard backlight. The firmware API for it is implemented
via WMI.
To make the backlight userspace configurable this driver emulates a
LampArray HID device and translates the input from hidraw to the
corresponding WMI calls. This is a new approach as the leds subsystem lacks
a suitable UAPI for per-key keyboard backlights, and like this no new UAPI
needs to be established.
The handle_* functions an corresponding structs are named based on the HID
spec: HID Usage Tables 1.6 -> 26 Lighting And Illumination Page (0x59)
