LibWeb: Implement CRC2D.imageSmoothingEnabled

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)
