crimson/os: specialize fmt::formater<> for types

since fmt v9, fmt::formatter<> is not specialized for the types with
operator<<(ostream&, ...) anymore. so we need to specialize it manually.
in this change, fmt::formatter<> is specialized for tree_stats_t and
test_item_t so the tree can compile with fmt v9.
