libstdc++: Enable vstring for wchar_t unconditionally [PR98725]
None of these vstring specializations depend on libc support for
wchar_t, so can be enabled unconditionally now that char_traits<wchar_t>
is always available.
libstdc++-v3/ChangeLog:
PR libstdc++/98725
* include/ext/rc_string_base.h [!_GLIBCXX_USE_WCHAR_T]
(__rc_string_base<wchar_t>): Define member function.
* include/ext/vstring.h [!_GLIBCXX_USE_WCHAR_T]
(hash<__gnu_cxx::__wvstring>): Define specialization.
* include/ext/vstring_fwd.h [!_GLIBCXX_USE_WCHAR_T] (__wvstring)
(__wsso_string, __wrc_string): Declare typedefs.
