tools/sched_ext: Add three-mask cmask intersection iterator

Add cmask_next_and2_set() and its round-robin wrap, extending
cmask_next_and_set() to a three-mask intersection: the next cid set in all
three masks at or after @start. A caller iterating the intersection of
three cmasks can then scan it in one pass, folding the third mask into the
word-level AND rather than skipping non-members one candidate at a time.
