Subject: score: Static Objects_Information initialization

Statically allocate the objects information together with the initial
set of objects either via <rtems/confdefs.h>.  Provide default object
informations with zero objects via librtemscpu.a.  This greatly
simplifies the workspace size estimate.  RTEMS applications which do not
use the unlimited objects option are easier to debug since all objects
reside now in statically allocated objects of the right types.

Close #3621.
