rtems: Fix rate monotonic statistics
The rate monotonic period statistics were affected by
rtems_cpu_usage_reset(). The logic to detect and work around a CPU
usage reset was broken.
The Thread_Contol::cpu_time_used is changed to contain the processor
time used throughout the entire lifetime of the thread. The new member
Thread_Contol::cpu_time_used_at_last_reset is added to contain the
processor time used at the time of the last reset through
rtems_cpu_usage_reset(). This decouples the resets of the CPU usage and
the rate monotonic period statistics.
Update #4528.
