Only allow calc() combinations as per spec.

We allowed calc expressions combining numbers and lengths, numbers and
percentages, and even a combination of numbers, percentages, and
lengths. None of those are allowed per the CSS Values and Units spec,
and it made it possible to combine user units, lengths, and percentages
into the same calc() for certain SVG CSS properties and attributes.

This improves SVG interop with Firefox. Firefox does not support calc()
for numbers, though.
