libstdc++: Adjust std::from_chars negative tests
Also test with an enumeration type. Move the dg-error directives outside the #if block, because DejaGnu would process them whether or not wchar_t support is present. libstdc++-v3/ChangeLog: * testsuite/20_util/from_chars/1_c++20_neg.cc: Check enumeration type. * testsuite/20_util/from_chars/1_neg.cc: Likewise. Move dg-error directives outside preprocessor condition.
