e_process: added a E_PROCESS_ACT_NO_VISIBLE_WINDOWS in E_Process_Action enumeration

There was a requirement that the specified process wants to get an event when process' windows are all unviewable.
So, we added E_PROCESS_ACT_NO_VISIBLE_WINDOWS enumeration and sent it when process' all windows were hidden.
