Use the same logic for lerp bias for color and alpha
It doesn't make sense for alpha to add the bias ONLY when dividing by 2, while color doesn't apply the bias for divide by 2 only; hardware testing indicates that alpha should have the bias.
This fixes the menus in Mario Kart Wii (https://bugs.dolphin-emu.org/issues/11909) but reintroduces the white rectangle in Fortune Street.
This reverts commit 5aaa5141ed76acc3fffc70561a6b6e7fe3b9b470 (and several other matching changes elsewhere).
