sched/clock: Provide !HAVE_UNSTABLE_SCHED_CLOCK stub for sched_clock_stable()
When CONFIG_HAVE_UNSTABLE_SCHED_CLOCK is disabled, sched_clock() is
already assumed to provide stable semantics, but the public header
doesn't provide a sched_clock_stable() stub for that case.
Add a header stub that always returns true and clean up the duplicate
local stub in ring_buffer.c, so callers can use sched_clock_stable()
unconditionally.
