Wrap the EFI_HII_CONFIG_ACCESS_PROTOCOL.CallBack to EFI_FORM_CALLBACK_PROTOCOL.Callback. Therefor,
the framework HII module willl do no porting (except some porting works needed for callback for EFI_ONE_OF_OPTION opcode)
and still work with a UEFI HII SetupBrowser.
@param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param Action Specifies the type of action taken by the browser. See EFI_BROWSER_ACTION_x.
@param QuestionId A unique value which is sent to the original exporting driver so that it can identify the
type of data to expect. The format of the data tends to vary based on the opcode that
generated the callback.
@param Type The type of value for the question. See EFI_IFR_TYPE_x in
EFI_IFR_ONE_OF_OPTION.
@param Value A pointer to the data being sent to the original exporting driver. The type is specified
by Type. Type EFI_IFR_TYPE_VALUE is defined in
EFI_IFR_ONE_OF_OPTION.
@param ActionRequest On return, points to the action requested by the callback function. Type
EFI_BROWSER_ACTION_REQUEST is specified in SendForm() in the Form
Browser Protocol.
@retval EFI_UNSUPPORTED If the Framework HII module does not register Callback although it specify the opcode under
focuse to be INTERRACTIVE.
@retval EFI_SUCCESS The callback complete successfully.
@retval !EFI_SUCCESS The error code returned by EFI_FORM_CALLBACK_PROTOCOL.Callback.
