rtems: Add rtems_scheduler_get_processor()
Add rtems_scheduler_get_processor() as a replacement for
rtems_get_current_processor(). The rtems_get_current_processor() is a
bit orphaned. Adopt it by the Scheduler Manager. This is in line with
the glibc sched_getcpu() function.
Deprecate rtems_get_current_processor().
Update #3731.
