SI-8346: Rebuild invariant sets in #toSet, avoiding CCE.
SI-3953 caused several types of sets' operations to trivially throw
`ClassCastException` after using inherited covariant #toSet method, by
doing an unchecked cast that is only safe for intrinsically covariant
set data structures like `HashSet`, but totally unsafe for others like
`TreeSet` or `Enumeration.ValueSet`.
This change moves the cast to the leaves of the class hierarchy where
that is safe, and incidentally undeprecates overriding Set#toSet.
