Rename resolveReflectionAttributeClassNames to resolveReflectionAttributeType and return Type directly

Instead of returning class name strings that get wrapped in GenericObjectType
by the caller, the helper method now accepts the classType parameter and
returns the final GenericObjectType or UnionType directly. This avoids the
unnecessary TypeCombinator::union call in the single-match case.
