wlr_scene: Fix missing calls to scene_node_update_outputs

Browse source 
There were a couple places this was missing
 - on mode change of an output. If the resolution changes for example
   nodes may fall out of the view.
 - on commits on an output for scale or transform changes
 - when the transform of a buffer is changed. If the dest size is not
 set, the buffer may have been rotated potentially changing its size
 if the buffer width != height
