fix: make sure isDefEqOffset does not expose kernel nat literals
...
This issue is similar to a bug where `isDefEqOffset` was exposing
`Nat.add` when processing `HAdd.hAdd`.
Fixes #561
The example at issue #561 is now working, but we may have other places
where raw literals are being accidentally exposed.

refactor: Add MkMatcherInput.
...
Since we are going to make `mkMatcher` reversible, it's quite useful to have the input be a `structure`. This way we make sure, that the inverse function always returns the same type as `mkMatcher` needs as input.
