f974dba2 - [6.2][cxx-interop] Fix name mangling for reference types

[6.2][cxx-interop] Fix name mangling for reference types Explanation: When generating type names for template instantiations for name mangling we did not generate correct names for reference types resulting in collisions in the mangled names. Issues: rdar://157237301 Original PRs: #83176 Risk: Low, the generated string is only used for name mangling. Testing: Added a compiler test. Reviewers: @egorzhdan
