CTCaer 7e26be6587 lvgl: Optimize color blending
The manual optimization done dramatically increases performance in software color blending.
Isolated gains reach 20-30%.

Color blending calculates 2 +1 color channels instead of the expensive 1+1+1 calculations.

This is as best as it gets without going in asm optimizations.
