libstdc++: Fix use-after-free in std::format [PR119671]
When formatting floating-point values to wide strings there's a case
where we invalidate a std::wstring buffer while a std::wstring_view is
still referring to it.
libstdc++-v3/ChangeLog:
PR libstdc++/119671
* include/std/format (__formatter_fp::format): Do not invalidate
__wstr unless _M_localized returns a valid string.
* testsuite/std/format/functions/format.cc: Check wide string
formatting of floating-point types with classic locale.
