Update links between ty-module and binders

The order might have been reversed at some point, leading to the two
chapters talking about each other in the wrong order.

+`ReLateParam` is conceptually a `Placeholder` that is always in the root universe (`U0`). It is used when instantiating late bound parameters of functions/closures while inside of them. Its actual representation is relatively different from both `ReEarlyParam` and `RePlaceholder`:
 - A `DefId` for the item that introduced the late bound generic parameter
 - A [`BoundRegionKind`] which either specifies the `DefId` of the generic parameter and its name (via a `Symbol`), or that this placeholder is representing the anonymous lifetime of a `Fn`/`FnMut` closure's self borrow. There is also a variant for `BrAnon` but this is not used for `ReLateParam`.

 As a concrete example, accessing the signature of a function we are type checking will be represented as `EarlyBinder<Binder<FnSig>>`. As we are already "inside" of these binders, we would call `instantiate_identity` followed by `liberate_late_bound_regions`.
