[clang-tidy] fix debug-only test failure

The clang-tidy/infrastructure/pr37091.cpp test inherits the top-level .clang-tidy configuration because it doesn't specify its own checks. It'd be a more stable test if it operates independently of the top-level .clang-tidy settings.

I've made the clang-tidy/infrastructure/pr37091.cpp test independent of the top-level .clang-tidy (picked an arbitrary check that I saw another clang-tidy/infrastructure test was also using: clang-tidy/infrastructure/temporaries.cpp)
