Fix T57457: animated image sequences not working in Eevee.

The dependency graph now handles updating image users to point to the current
frame, and tags images to be refreshed on the GPU. The image editor user is
still updated outside of the dependency graph.

We still do not support multiple image users using a different current frame
in the same image, same as 2.7. This may require adding a GPU image texture
cache to keep memory usage under control. Things like rendering an animation
while the viewport stays fixed at the current frame works though.
