Split Classic API data instantiation into individual files. This reduces the size of the BSS section when an optional manageer stub is used. Some tests showed about a 600 byte reduction in BSS size. Also eliminated the variables _RTEMS_tasks_User_initialization_tasks and _RTEMS_tasks_Number_of_initialization_tasks because they were only used in one place after initialized. It was a waste of space.
