signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
The header tracehook.h is no place for code to live. The functions
set_notify_signal and clear_notify_signal are not about signals. They
are about interruptions that act like signals. The fundamental signal
primitives wind up calling set_notify_signal and clear_notify_signal.
Which means they need to be maintained with the signal code.
Since set_notify_signal and clear_notify_signal must be maintained
with the signal subsystem move them into sched/signal.h and claim them
as part of the signal subsystem.
