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.
