libstdc++: Fix 29_atomics/headers/atomic/types_std_c++2a_neg.cc for C++23
This test fails when run as C++23 because the <bits/stdc++.h> PCH
includes <stdatomic.h> which declares ::memory_order, invalidating the
test's assumptions. Disable PCH so that the test verifies that <atomic>
doesn't declare ::memory_order, as originally intended.
Also fix the using-declaration which would be invalid even if the type
was declared in the global namespace, and adjust the expected error.
libstdc++-v3/ChangeLog:
* testsuite/29_atomics/headers/atomic/types_std_c++2a_neg.cc:
Fix test to work for C++23 and C++26 too.
