libstdc++: Rename tests like .../wchar_t/1.cc to .../wchar_t.cc

There's no need to have directories containing a single test file, we
can rename the files to the directory names and remove the directories.

The dejagnu proc that filters out wchar_t tests just checks for
"wchar_t" anywhere in the path, so will work just as well on wchar_t.cc
or constexpr-wchar_t.cc paths.
