This commit adjusts the expected error messages in the libstdc++ test suite for mdspan negative tests. The changes focus on accurately reflecting that errors arise from static_assertion failures during template instantiation, rather than during evaluation in an expanded context. This ensures the test suite correctly validates error reporting for compile-time checks related to mdspan layouts and submdspan canonical slices.
