Call CheckCanStartAnimationOnCompositor at paint

Note: this is for background-color animation only, not for other
properties.

When composite background-color animation, the paint stage collect
some parameters such as animated colors for the animation. If this
step is successful, then we will paint the element off the main
thread. After that, we can have CheckCanStartAnimationOnCompositor
returning false and refuse to run the background-color animation
on the compositor thread. In this case, the paint of the element
off the main thread won't work.

So in this CL, we call CheckCanStartAnimationOnCompositor during
the paint step. This ensures the consistency of the paint and
compositor animation.
