[clang] [clang][NFC] Add marking to CWG2947 test (PR #181832)

[Vlad Serebrennikov via cfe-commits]

https://github.com/Endilll created https://github.com/llvm/llvm-project/pull/181832

052f2f8cd17f3ff8bcb7b53a777a232d9ac36965 accidentally changed the status of CWG2947 from "Clang 23" to "No", because the test was missing the special comment that `make_cxx_dr_status` scripts consumes. This PR adds the special comments and restores the original status of CWG2947.
