score: Use common names for per-CPU variables

Use "cpu" for an arbitrary Per_CPU_Control variable.

Use "cpu_self" for the Per_CPU_Control of the current processor.

Use "cpu_index" for an arbitrary processor index.

Use "cpu_index_self" for the processor index of the current processor.

Use "cpu_count" for the processor count obtained via
_SMP_Get_processor_count().

Use "cpu_max" for the processor maximum obtained by
rtems_configuration_get_maximum_processors().
