Per UEFI spec, FORM_OPEN/FORM_CLOSE Callback function should be called for each question in the form when this form opens or closes.
Update SetupBrowser driver to call Callback function (FORM_OPEN/FORM_CLOSE) based on UEFI spec, and update all EDKII HII drivers to correctly handle FORM_OPEN and FORM_CLOSE call back.
