Update column order in MSW native wxHeaderCtrl after drag.

We must update the internally stored columns order even if the end reorder
event was processed (but not vetoed), otherwise we don't reflect the new order
in the our public functions such as GetColumnsOrder() which broke wxDVC
display under MSW.

Closes #11300.
