Simplify Set initialization and reduce the overhead of creating extra collections. The changes mostly include: - new HashSet<>(List.of(...)) - new HashSet<>(Arrays.asList(...)) / new HashSet<>(asList(...)) - new HashSet<>(Collections.singletonList()) / new HashSet<>(singletonList()) - new HashSet<>(Collections.emptyList()) - new HashSet<>(Set.of()) This change takes the following into account, and we will not change to Set.of in these scenarios: - Require `mutability` (UnsupportedOperationException). - Allow `duplicate` elements (IllegalArgumentException). - Allow `null` elements (NullPointerException). - Depend on `Ordering`. `Set.of` does not guarantee order, so it could make tests flaky or break public interfaces.
