Invalidate wxDataViewCtrl bests widths on expand/collapse.

Browse Source 
The best column widths are computed from "realized" items that are
available as rows in wxDataViewCtrl. This information changes when a
previously collapsed node is expanded and new items become available for
column width calculation.

Fixes #14167.
