    libstdc++: Do not use facets cached in ios for ATL128 build [PR103387]

    For the powerpc64le build with two different long double
    representations, we cannot use the ios_base::_M_num_put and
    ios_base::_M_num_get pointers, because they might have been initialized
    in a translation unit using the other long double type. With the changes
    to add __try_use_facet to GCC 13 the cache isn't really needed now, we
    can just access the right facet in the locale directly, without needing
    RTTI checks.

    libstdc++-v3/ChangeLog:

            PR libstdc++/103387
            * include/bits/istream.tcc (istream::_M_extract(ValueT&)): Use
            std::use_facet instead of cached _M_num_get facet.
            (istream::operator>>(short&)): Likewise.
            (istream::operator>>(int&)): Likewise.
            * include/bits/ostream.tcc (ostream::_M_insert(ValueT)): Use
            std::use_facet instead of cached _M_num_put facet.=
