REF: UEFI_Spec_2_10_Aug29.pdf page 1695.
In 35.5.4 EFI_HII_CONFIG_ACCESS_PROTOCOL.CallBack():
If the callback function returns with the ActionRequest set to
_QUESTION_APPLY, then the Forms Browser will write the current modified
question value on the selected form to storage.
Update the SetupBrowserDxe, if callback function return
EFI_BROWSER_ACTION_REQUEST_QUESTION_APPLY, then call SetQuestionValue
with GetSetValueWithHiiDriver to apply the change immediately.
