Workaround P3168 causing ambiguous overload issues with StringMaker

Browse Source 
P3168 turned `std::optional` into a range type, so the partial specialization
of `StringMaker` for `std::optional<T>` conflicted with the partial
specialization for range types. Ideally we will fix this in the future
to support user-provided partial specializations for range-like types,
but for now we just disable the partial specialization for `std::optional<T>`
if P3168 is implemented.
