Implement BoxedRep proposalwip/boxed-rep
This implements the BoxedRep proposal, refactoring the `RuntimeRep`
hierarchy from:
```haskell
data RuntimeRep = LiftedPtrRep | UnliftedPtrRep | ...
```
to
```haskell
data RuntimeRep = BoxedRep Levity | ...
data Levity = Lifted | Unlifted
```
Updates binary, haddock submodules.
Closes #17526.
