Summary [Qt] Optimize ImageBuffer::getUnmultipliedImageData

In getImageData we do slow conversion of multiplied to premultiplied and back, that could be done faster by Qt. Additionally we create Color objects that have input verification, when all we need is the RGB32 value which is identical to QRgb.
