LibWeb: Remove transform interpolation optimization

The property values here will always be StyleValueLists and not
TransformationStyleValues. The handling of interpolation in this case
gets quite a bit more complex, so let's just remove the dead code for
now and attempt this optimization again in the future if it's needed.
