[AnyPropagation] Any propagation for TypeT lower bounds
[AnyPropagation] Any propagation for TypeT lower bounds

Summary: Implements any propagation for `TypeT` lower bounds, which should covariantly flow the type in the `TypeT` to `any`. This is required for `any`-propagation on `ObjT` and `InstanceT` because `any` can be used as a class type in this context.
