[10115] Add function to update model_info at changes to scale or model.

Browse source 
* At every change to model or scale, the related data (bounding_radius/combat_reach) is now updated accordingly (note that player combat_reach are not changed like creature).
* UpdateModelData is called from within SetDisplayId while changes to scale has explicit call to UpdateModelData after new scale is set (mostly for aura scale)
* The updated values are calculated by (scale*bounding_radius)/(scale*combat_reach)
* Database values for bounding_radius/combat_reach are expected to be relative to scale like 1.0
