Add ComboBox::close_behavior (#5305)

Browse Source 
Exposed the underlying PopupCloseBehavior of ComboBox in order to allow
more control of ComboBox behavior.

This allows ComboBox to be used rather than manually managing a popup
directly, while also gaining the convenience features of ComboBox such
as popup auto-sizing.
