    libstdc++: Add std::time_get %r support [PR71367]

    This incremental patch adds std::time_get %r support (%p was added alre=
ady
    in the previous patch).  The _M_am_fm_format method previously in the
header
    unfortunately had wrong arguments and so was useless, so the largest
    complication in this patch is exporting a new symbol in the right symbol
    version.
