score: Introduce scheduler nodes

Rename scheduler per-thread information into scheduler nodes using
Scheduler_Node as the base type. Use inheritance for specialized
schedulers.

Move the scheduler specific states from the thread control block into
the scheduler node structure.

Validate the SMP scheduler node state transitions in case RTEMS_DEBUG is
defined.
