score: Optimize _Thread_queue_Enqueue()

Move thread state for _Thread_queue_Enqueue() to the thread queue
context.  This reduces the parameter count of _Thread_queue_Enqueue()
from five to four (ARM for example has only four function parameter
registers).  Since the thread state is used after several function calls
inside _Thread_queue_Enqueue() this parameter was saved on the stack
previously.
