Vadim Zeitlin e911dd0a5a Hide combobox popup when it is hidden itself in wxMSW.
It was possible to hide the main part of a combobox control but keep its popup
shown and this notably happened in wxGrid when TAB was pressed while a
wxChoice cell editor was dropped down.

Avoid this Cheshire combobox syndrome by explicitly dismissing the popup when
a combobox is hidden.

Closes #3113.
