sched/core: Make policy-testing consistent
Most of the policy-tests are done via the <class>_policy() helpers with the notable exception of idle. A new wrapper for valid_policy() has also been added to improve readability in set_load_weight(). This commit does not change the logical behavior of the scheduler core.
