Improve performance showing axes on large drawings by showing only the axes of the top model

There is a new config option is available:

show_axes_by_view_scope

With that option selecting axes in the datum tab of the "Show Model Annotiations" dialog (see below) can be configured to show only the axes of the top model, not all the axes of the e.g. 50000 submodels.

• all_sub_models (the default value)
  • All axes of all submodels are shown which is slow for comprehensive models
  • This is the default behavior in the datum tab in the Show Model Annotation dialog and leads to not responding sessions
  • Example of time consuming display of a lot of axes with that config setting:
    
    
    
    
• top_model_only
  • Only the axes of the top model are shown (which is fast)
  • This setting prevents not responding sessions on large drawings

This implements the idea 1314 with the solution suggestion "Idea A" described here:

Keep Creo Elements/Pro responsive when "Show Model Annotiations" for all datum features is selected on a comprehensive drawing view

There is still Idea B to improve the performance keeping the actual default behaviour:

Implement a stop button, to cancel that action if Creo Elements/Pro does not respond in that situation. Try to use the existing stop button which can be used e.g. during model retrieval.
