[vm/aot] Make mixin deduplication transformation more robust wrt new mixins

Previously, mixin deduplication transformation expected that isAnonymousMixin
classes could occur only in a superclass position. After this change,
deduplication also handles (canonicalizes) isAnonymousMixin classes in
implementedTypes, as CFE uses isAnonymousMixin classes in implementedTypes
to represent superclass constraints for mixin declarations.
No other uses of isAnonymousMixin classes supported.
