Improve overlap error for polykinded constraints
There were two problems around `mkDictErr`:
1. An outdated call to `flattenTys` meant that we missed out on some
instances. As we no longer flatten type-family applications,
the logic is obsolete and can be removed.
2. We reported "out of scope" errors in a poly-kinded situation
because `BoxedRep` and `Lifted` were considered out of scope.
We fix this by using `pretendNameIsInScope`.
fixes #20465
