Daniel Sainati 2a479a6953 remove deprecated utilities ... Summary: Remove `$Subtype` and `$Supertype` utilities. Replacement was done on a best-effort basis. In many cases it sufficed to replace `$Supertype<T>` and `$Subtype<T>` with `T`, but when this was not possible `any | T` and `any & T` were used instead.
