sched/headers: sched/clock: Mark all functions 'notrace', remove CC_FLAGS_FTRACE build asymmetry

Mark all non-init functions in kernel/sched.c as 'notrace', instead of
turning them all off via CC_FLAGS_FTRACE.

This is going to allow the treatment of this file as any other scheduler
file, and it can be #include-ed in compound compilation units as well.
