If a calculation was simplified down to a single numeric node, then most of the time we can instead return a regular StyleValue, for example `calc(2px + 3px)` would be simplified down to a `5px` LengthStyleValue. This means that parse_calculated_value() can't return a CalculatedStyleValue directly, and its callers all have to handle non-calculated values as well as calculated ones. This simplification is reflected in the new test results. Serialization is not yet correct in all cases but we're closer than we were. :^)
