wlr_scene: Don't damage when setting opaque region 

Opaque region is a optimization hint, (bugs outstanding) it will not
change the output contents, therefore damage does not need to be submitted.

However, we still need to update the visibility state of the other
nodes in the tree. To do this call scene_update_region() by ourselves
but not `scene_node_update()` which will damage the outputs.
