LibWeb: Support more CSS image-rendering values

Browse source 
This patch adds support for "crisp-edges", "high-quality" and "smooth"
for the CSS image-rendering property.

"crisp-edges" maps to nearest-neighbor scaling for <canvas> and <img>
elements, while "high-quality" and "smooth" both use bilinear blending.
