Reviewed by Antoine Quint.
Fixes a crash due to how the VisitedAffectedStyleTypeWrapper interpolation
wrapper worked when the unvisited and visited styles returned different
"can interpolate" values, acting as if both could interpolate if either
was able to. Instead, we now cache the individual responses and construct
separate contexts before calling interpolate.
