Now that we always use types2 to validate user source code, we can remove the constSet logic from typecheck for detecting duplicate expression switch cases and duplicate map literal keys. This logic is redundant with types2, and currently causes unified IR to report inappropriate duplicate constant errors that only appear after type substitution. Updates #42758.
