Remove infinities from Animation::TimeToEffectChange()

This method was using std::numeric_limits<double>::infinity() to
represent an animation that was no longer in effect. Instead of
using infinities we could better change the return type to
base::Optional<double> and simply return base::nullopt instead
of the infinity value.

This will ease the transition to using AnimationTimeDelta instead
of a double.
