score: Add _CPU_Use_thread_local_storage()
At some point during system initialization, the idle threads are created.
Afterwards, the boot processor basically executes within the context of an idle
thread with thread dispatching disabled. On some architectures, the
thread-local storage area of the associated thread must be set in dedicated
processor registers. Add the new CPU port function to do this:
void _CPU_Use_thread_local_storage( const Context_Control *context )
Close #4672.
