LibWeb: Make CSSPixels and Length use 64-bit (double) floating point
This fixes a plethora of rounding problems on many websites. In the future, we may want to replace this with fixed-point arithmetic (bug #18566) for performance (and consistency with other engines), but in the meantime this makes the web look a bit better. :^) There's a lot more things that could be converted to doubles, which would reduce the amount of casting necessary in this patch. We can do that incrementally, however.
