[clang] [clang] [TargetCXXABI] Fix -Wextra-semi warning (NFC) (PR #96982)

[via cfe-commits]

https://github.com/akirchhoff-modular created https://github.com/llvm/llvm-project/pull/96982

While building a downstream project including `TargetCXXABI.h`, I received a `-Wextra-semi` warning.  This PR removes the extra semicolon, fixing the warning.
