Backlight - New option : BACKLIGHT_CAPS_LOCK (#4769)
* [BACKLIGHT_CAPS_LOCK_INDICATOR] Use backlight toggling as Caps Lock LED I've implemented this feature because S65-X doesn't have LED indicators and the existing led_set_kb(usb_led) function try to use backlight as indicator but that creates an inconsistency with backlight_config state. - define `BACKLIGHT_CAPS_LOCK_INDICATOR` to enable Caps Lock indicator using backlight (for keyboards without dedicated LED) - Don't turn off LED indicators when suspend because backlight is already turned off. Else led_set(0) will turn back on backlight. - Documentation has been updated * [BACKLIGHT_CAPS_LOCK_INDICATOR] Turn off all LED indicators except Caps Lock if BACKLIGHT_CAPS_LOCK_INDICATOR * [BACKLIGHT_CAPS_LOCK] Rename BACKLIGHT_CAPS_LOCK_INDICATOR * [BACKLIGHT_CAPS_LOCK] Use new IS_LED_ON method
