SVG parsing allows calc() for <number>

The SVG spec says[1] to allow \<number> when parsing values for
presentation attributes to allow unitless lengths for things like
font-size in the attribute.

The CSS specification says calc() with numbers is allowed wherever
\<number> is allowed. Blink is the only browser to allow calc()
expressions for \<number>. It is possible we should change that, but as
long as we accept it at parse time, we should handle it when applying it
to the ComputedStyle.

This CL computes font-size lengths for calc() expressions with numbers.
