Make `unordered_multimap` constexpr as part of P3372R3.
Note that `node-handle::key()` is intentionally left not constexpr, and the constexpr-ness largely requires a user-defined hash functor.
Feature-test macro (also covers constexpr `unordered_map`):
```C++
#define __cpp_lib_constexpr_unordered_map 202502L // also in <unordered_map>
```
