  [C++20] [Modules] Don't create duplicated deduction guides for duplicated classes

Close https://github.com/llvm/llvm-project/issues/56916

Within C++20 modules, we may have multiple same constructors in
multiple same RecordDecls. And it doesn't make sense naturally to create
duplicated deduction guides for the duplicated constructors.
