1. Reposition dropdown whenever items are selected …

   This fixes an old bug where if you had a multiple select with the
   `closeOnSelect` option set to `false` and many options being
   selected, the dropdown would not reposition itself if the selected
   options expanded the container down another line. This was because
   the dropdown was only being repositioned when it was opened, closed,
   or if something around it was scrolled or resized. Unfortunately,
   in most cases none of these happened and the dropdown would start
   covering the selections.
   
   This was fixed by telling Select2 to resize the dropdown when new
   options are selected or existing options are unselected.
   
   Fixes #4377

2. Attach positioning handlers at bind time …

   The positioning handlers have been attached at the time that the
   dropdown is opened since when they were first committed many years
   ago. It's not actually clear why this was being done, since they
   don't rely on anything involving the dropdown being open. This
   removes the flag and process for setting these handlers only after
   the dropdown was opened for the first time, and moves these handlers
   to always be set at bind time.
