score: Optimize object lookup

Use the maximum ID for the ID to object translation. Using the maximum
ID gets rid of an additional load from the object information in
_Objects_Get(). In addition, object lookups fail for every ID in case
the object information is cleared to zero. This makes it a bit more
robust during system startup (see new tests in spconfig02).

The local table no longer needs a NULL pointer entry at array index
zero. Adjust all the object iteration loops accordingly.

Remove Objects_Information::minimum_id since it contains only redundant
information. Add _Objects_Get_minimum_id() to get the minimum ID.

Update #3621.
