platform/x86: asus-wmi: Implement TUF laptop keyboard power states

Browse Source 
Adds support for setting various power states of TUF keyboards.
These states are combinations of:
- boot, set if a boot animation is shown on keyboard
- awake, set if the keyboard LEDs are visible while laptop is on
- sleep, set if an animation is displayed while the laptop is suspended
- keyboard (unknown effect)

Adds two sysfs attributes to asus::kbd_backlight:
- kbd_rgb_state
- kbd_rgb_state_index
