Add CSSMathExpressionNumericLiteral canonical units eager simplification

Spec def: "If root is a dimension that is not expressed in its canonical unit, and there is enough information available to convert it to the canonical unit, do so, and return the value." https://w3c.github.io/csswg-drafts/css-values/#calc-simplification However, Numbers should not be eagerly simplified at this time since that would result in converting Integers to Doubles (kNumber, canonical unit for Numbers).
