This patch cleans up SVGLengthContext::valueForLength. If we review all conditions, we can find that only
three LengthType needs to be handled in this place, Percent, Fixed, and Calculated. And we can know that
we do not need to compute viewport size when LengthType is Fixed. This patch changes it so that we no longer
need to compute it when LengthType is Fixed.
