rgblight split transfer non-eeprom config (#5396)
* Make rgblight_update_dword not update eeprom (we already have eeconfig_update_rgblight for that). Make split i2c keyboards transfer active rgblight config rather than eeprom saved version of rgblight config, enabling runtime changes that aren't persisted to eeprom. * prev_level and prev_rgb only store successfully transmitted values
