Send wxEVT_DATAVIEW_COLUMN_REORDERED in generic wxDataViewCtrl

Simply translate wxEVT_HEADER_END_REORDER into this event, which was
previously only sent by the macOS version.

GtkTreeView doesn't seem to support column drag-and-drop at all, so this
event is still never generated by wxGTK.

Closes #14297.
