Don't depend on layout to do getComputedStyle() on border-radius

border-radius and its longhands are defined to return resolved values
instead of used values, this means a layout is not required to compute
the result of getComputedStyle() on these properties.
This patch fixes getComputedStyle() of border radius properties to
return calc objects instead of resolving them to absolute pixel values.

Relevant spec:
