Show progress dialog during startup (#9255) 
* Show progress dialog during startup for selection enumeration that can take a long time.

* Updated with better code organization and a timer to ensure the progress dialog does not appear in most cases.

* Update based on PR feedback

* Change progress dialog delay from 1500ms to 2500ms

* Move progress dialog invocation off the main UI thread
