Rename animatable to interpolable in CSSProperties.in

Rename animatable to interpolable in CSSProperties.in

This change renames isAnimatableProperty() to isInterpolableProperty()
and renames isAllowedAnimation() to isAnimatableProperty().

This is to avoid confusion about whether a property can be animated
versus whether it will interpolate smoothly when animated and to bring
our implementation closer to a recent working group decision regarding
the name "animatable" for CSS properties:

Unfortunately it's still correct. Added TODO in CSSAnimations.cpp to be spec
compliant.
