LibWeb: Implement CRC2D.imageSmoothingEnabled

Browse source 
We now select between nearest neighbor and bilinear filtering when
scaling images in CRC2D.drawImage().

This patch also adds CRC2D.imageSmoothingQuality but it's ignored for
now as we don't have a bunch of different quality levels to map it to.

Work towards #17993 (Ruffle Flash Player)
