The plan for #20264 is to introduce let-bound types to have observable sharing in types.
To avoid the need to carry an environment when dealing with occurrences of these type variables,
we embed the types they're bound to (if any) in a `tv_unfolding :: Maybe Type` attribute.
This way, one can look through let-bound type variables using `coreView` and friends.
In particular, definitional equality looks through unfoldings.

During specialisation, a dictionary being specialised gets a new unfolding by turning
`DFun \ bndrs -> MkD @<T1> ... @<Tm> <op1> ... <opn>` into
`DFun \ spec_bndrs -> MkD @((\ bndrs -> TYPE: <T1>) spec_args) ... ((\ bndrs -> <opn>) spec_args)`
which in turns gets beta-reduced into
`DFun \ spec_bndrs -> MkD (let { bndrs = spec_args } in TYPE: <T1>) ... (let { bndrs = spec_args } in <opn>)`.
Previously, such let binders would immediately be substituted into the type so it didn't cause any issue,
but now we want to avoid inlining.
Arguments of the form `let { bndrs = spec_args } in TYPE: <T1>` are not considered as type arguments since they're
not of the canonical form `TYPE: something`.
This commit restores the previous behavior of substituting the specialised type arguments.
Alternatively, we could attach some floated type bindings to `DFun`s.

In order to find out let-bound type variables that are used only once, in the hope of inlining them,
we need to track type variables as well in the occurrence analiser. Just like Id's, we attach an
`OccInfo` to each (immutable) type variable, and we walk into types and coercions to accurately gather
occurrences.

As a first attempt, ignore type-lets in CorePrep to avoid crashes.
However, this is not enough: CorePrep also does some let-floating.
If we don't float type-lets along with value-level let-bindings,
the latter can float out of the scope of a type variable in use.

IfaceLetBndr isn't fit to represent type-let binders, as it includes a
bunch of vacuous flags for Ids only.
Instead of putting squares in circles, I added a new constructor for type binders.
The downside is that it breaks existing iface files, so since we can't bootstrap
yet so we have to bootstrap a cherry-picked branch and then checkout again to build
with --freeze1.
To avoid similar issues in the future, IfaceTyVarInfoItem serialises with a tag
despite there being only one constructor for now.
