sched/headers: Split out open-coded prototypes into kernel/sched/smp.h

Browse Source 
Move the prototypes for sched_ttwu_pending() and send_call_function_single_ipi()
into the newly created kernel/sched/smp.h header, to make sure they are all
the same, and to architectures happy that use -Wmissing-prototypes.
