[clang] Make sure all C++ DR tests are running with -pedantic-errors (#94203)
In #94167 I found out that `cwg28xx.cpp` has been running without `-pedantic-errors` and fixed that. This patch fixes that for the rest of the test suite. Only one test was affected with a trivial fix (warning was escalated to an error). I'm intentionally leaving out test for CWG2390, because it requires major surgery. It's addressed in #94206.
