Original change's description:
> [BGPT] Remove XXXPaintPropertyNode::IsRunningXXXAnimationOnCompositor()
> 
> Recent investigation and discussions made it clear that
> ComputedStyle::IsRunningXXXAnimationOnCompositor() methods actually
> reflect the animation status from the compositor. The previous
> plan about using them was wrong because it caused a chicken-and-egg
> problem: we wanted them to inform the compositor to start animations,
> but they actually came from the compositor after animations were
> started.
> 
> Now use ComputedStyle::IsRunningXXXAnimationOnCompositor() only to
> ignore changes of animation values at blink side. Changes of the flags
> themselves no longer need to be handled by blink in any way.
> 
> Bug: 935770
