Animation: update image active frame when update the rendering (#36286)

Browse source 
When no CSS animation exist, register timer for image animation, update
animated image active image frame as part of update_the_rendering, mark
node as dirty if the corresponding image need update. Added unit test to
test ImageAnimationState.

Part of https://github.com/servo/servo/issues/36057, the last step to
let the Animated Image "Move".

Testing: Introduced new WPT RefTest for animated image, but fail because
of https://github.com/servo/servo/issues/36931. New unit test for
`ImageAnimationState`.
Fixes: https://github.com/servo/servo/issues/22903
