style: Don't allow negative radii in radial gradients.

Mostly renaming for clarity, as the gradient parsing code is a bit hairy.

This also changes -webkit- gradients, which is, I think, the right thing to do
(otherwise I need to give up on the type system and sprinkle parse_non_negatives
around, which would be unfortunate).

I filed https://bugs.chromium.org/p/chromium/issues/detail?id=1008112 on
Chromium still accepting negative radii for those, so will wait to submit the
patch for review until they reply there with their intentions.
