blimp: Update animation policy for images on the blimp engine.

The Blimp Engine currently uses the default animation policy in blink,
which means for an image like a GIF the engine would trigger regular
commits to drive the animation. Change this to NO_ANIMATION, so only
the first frame of the animation is shown.
