When effect of adjustment layer strip is moved below the adjustment layer, this causes infinite loop in strip rendering. Same happens when you use multicam strip and set source channel to one of its effects. This is fixed by passing `SeqRenderState` to the effects. If any strip renders "seqbase" pointer of strip is stored in set in the render state struct. If the pointer exists in this set, function returns without rendering anything. In other words, The strip must never render itself. Pull Request: https://projects.blender.org/blender/blender/pulls/146624
