1) Process the axtra action or exit file explorer when user select one file .
2) update of file content if a dir is selected.
@param This Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
@param Action Specifies the type of action taken by the browser.
@param QuestionId A unique value which is sent to the original exporting driver
so that it can identify the type of data to expect.
@param Type The type of value for the question.
@param Value A pointer to the data being sent to the original exporting driver.
@param ActionRequest On return, points to the action requested by the callback function.
@retval EFI_SUCCESS The callback successfully handled the action.
