[test] lit.cfg: Wrap all substitutions with capture group refs in `SubstituteCaptures` Since https://github.com/llvm/llvm-project/pull/103042, backslashes in substitutions are consistently escaped on all platforms before feeding the substitutions to the regex engine. Make sure all substitutions containing capture group references are wrapped in `SubstituteCaptures` to suppress this behavior once main is rebranched.
