PmCheck: Use ConLikeSet to model negative info
In #17911, Simon recognised many warnings stemming from over-long list unions while coverage checking Cabal's `LicenseId` module. This patch introduces a new `PmAltConSet` type which uses a `UniqDSet` instead of an association list for `ConLike`s. For `PmLit`s, it will still use an assocation list, though, because a similar map data structure would entail a lot of busy work. Fixes #17911.
