<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Implement BoxedRep proposal

This implements the BoxedRep proposal, refacoring the `RuntimeRep`
hierarchy from:

```haskell
data RuntimeRep = LiftedPtrRep | UnliftedPtrRep | ...
```

to

```haskell
data RuntimeRep = BoxedRep Levity | ...
data Levity = Lifted | Unlifted
```

Closes #17526.
