score: Add Status_Control for all APIs

Unify the status codes of the Classic and POSIX API to use the new enum
Status_Control.  This eliminates the Thread_Control::Wait::timeout_code
field and the timeout parameter of _Thread_queue_Enqueue_critical() and
_MPCI_Send_request_packet().  It gets rid of the status code translation
tables and instead uses simple bit operations to get the status for a
particular API.  This enables translation of status code constants at
compile time.  Add _Thread_Wait_get_status() to avoid direct access of
thread internal data structures.
