score: PR2136: Fix _Thread_Change_priority()

Add call to _Scheduler_Schedule() in missing path after
_Thread_Set_transient() in _Thread_Change_priority(). See also
sptests/spintrcritical19.

Add thread parameter to _Scheduler_Schedule(). This parameter is
currently unused but may be used in future SMP schedulers.

Do heir selection in _Scheduler_Schedule(). Use
_Scheduler_Update_heir() for this in the particular scheduler
implementation.

Add and use _Scheduler_Generic_block().
