[PATCH] sched/isolation: Make CPU_ISOLATION depend on SMP or COMPILE_TEST

On uniprocessor systems, critical and non-critical tasks cannot be isolated, as there is only a single CPU core. Hence enabling CPU isolation by default on such systems does not make much sense. Instead of changing the default for !SMP, fix this by making the feature depend on SMP, with an
