score: Remove support for RTEMS_USE_16_BIT_OBJECT
The RTEMS_USE_16_BIT_OBJECT define is not set by an RTEMS port. Remove
support for 16-bit object identifiers. If someone really wants to use
RTEMS on a 16-bit target, then it is better to use self-contained
objects instead of playing around with object identifier optimizations.
Update #3603.
