If RGBLIGHT_EFFECT_BREATHE_CENTER is undefined, use fixed breathe table instead of exp() and sin() (#5484)
* If RGBLIGHT_EFFECT_BREATHE_CENTER is undefined, use fixed breathe table instead of exp() and sin() * Change rgblight breathing table size to be easily selectable. add RGBLIGHT_BREATHE_TABLE_SIZE macro for customize breathing effect.
