 Add _CPU_Counter_frequency()

 Add rtems_counter_frequency() API function.  Use it to initialize the
 counter value converter via the new system initialization step
 (RTEMS_SYSINIT_CPU_COUNTER).  This decouples the counter implementation
 and the counter converter.  It avoids an unnecessary pull in of the
 64-bit integer division from libgcc.

 Update #3456.
