Fix T96163: Image editor doesn't refresh when undo/redo.

Undo would invalidate image owned GPU textures only. Textures
that are owned by the editor were not refreshed. This patch would
invalidate all the GPU textures by marking the whole image dirty.

This can be improved later as we could add partial updates of GPU
textures.
