Add missing implementation for CSSMathClamp::toSumValue(). Sadly I couldn't
find the corresponding specification text for this so I filed:
- https://github.com/w3c/css-houdini-drafts/issues/1078

The specification is at [1] but currently fails to mention CSSMathClamp.
However, I implemented the same behavior as Blink for interoperability.
