  [libc++][test] Raise a useful error when no -std=c++NN flag is found to work (#99423)

Recently ran into an issue with symptoms very similar to
https://github.com/llvm/llvm-project/issues/56816 while attempting to
build and test libc++ on NixOS. The error message is cryptic (just
`StopIteration`), which was very annoying to track down. The error at
least saying "hey your compiler's bad" would have saved me quite a bit
of time figuring out the issue.
