Brad Fitzpatrick 1a963342c7 util/set: add Of variant of SetOf that takes variadic parameter
set.Of(1, 2, 3) is prettier than set.SetOf([]int{1, 2, 3}).

I was going to change the signature of SetOf but then I noticed its
name has stutter anyway, so I kept it for compatibility. People can
prefer to use set.Of for new code or slowly migrate.

Also add a lazy Make method, which I often find myself wanting,
without having to resort to uglier mak.Set(&set, k, struct{}{}).

util/set: implement json.Marshaler/Unmarshaler (#10308)
Marshal as a JSON list instead of a map. Because set elements are
`comparable` and not `cmp.Ordered`, we cannot easily sort the items
before marshaling.
