LibWeb: Simplify standalone CSS math functions when used outside calc()

Browse Source 
Math functions like abs(), clamp(), round(), etc, can be used by
themselves in property values, without wrapping them in calc().

Before this change, we were neglecting to run calc simplification on the
generated calculation node trees. By doing that manually after parsing a
standalone math function, we score at least a couple hundred WPT points.
